ABSTRACT

El tinnitus es la sensación de sonido en ausencia de cualquier fuente externa. Nuestro objetivo fue evaluar la repercusión del tinnitus en la calidad de vida. Se inscribieron 25 pacientes con tinnitus con una amplia gama de umbrales de pérdida auditiva (HLT) y estado de gravedad de tinnitus. La gravedad, la ansiedad y la depresión del tinnitus se evaluaron mediante el inventario de discapacidades por tinnitus (THI), el índice funcional de tinnitus (TFI) y la escala de ansiedad y depresión hospitalaria (HADS), respectivamente. Se realizó una audiometría de conducción aérea de tono puro. El impacto de la percepción del tinnitus en la calidad de vida se encontró más alto en el grupo de sufrimiento. La escala de ansiedad y depresión figuraba en 40% y 60%, respectivamente. El uso de la mano fue de 20 diestros y 5 zurdos. El tinnitus bilateral se está experimentando en el 76%. El LH se presentó en 17 (68%) de los pacientes con tinnitus. La descripción del sonido del tinnitus como silbido (40%), siseo (24%), pulsante (16%), timbre (8%) y ruidos de tono alto (12%). Con respecto al cuestionario THI, los sujetos con tinnitus se dividen en 60% (leve), 30% (moderado) y 10% (grave). Mientras que el cuestionario TFI, el 50% mostró un (leve), el 25% (moderado) y el 25% mostró (severo). Postulamos una fuerte asociación positiva significativa entre HADS y la gravedad del tinnitus: THI (P = 0,000) y TFI (P = 0,001). Esos datos revelaron que la percepción del tinnitus tiene impactos negativos en la calidad de vida mientras que la gravedad puede verse alterada por la lateralidad


Tinnitus is the sensation of sound in the absence of any external source, and the aim is to assess the impaction of tinnitus on QoL. 25-tinnitus sufferers were enrolled with a wide range of hearing loss thresholds (HLT) and tinnitus severity status. Tinnitus severity, anxiety and depression were assessed using tinnitus handicap inventory (THI), tinnitus functional index (TFI), and the hospital anxiety and depression scale (HADS), respectively. Pure tone air conduction audiometry was performed. The impaction of tinnitus perception on QoL was found higher in suffering group. The anxiety and depression scale figured in 40%, and 60%, respectively. The handed use was 20 rights handed and 5 left-handed. Bilateral tinnitus is experiencing in 76%. The HL occurred in 17(68%) of tinnitus patients. The description of tinnitus sound as whistling (40%), hissing (24%), pulsating (16%), ringing (8%), and high pitch noises (12%). Regarding THI questionnaire, tinnitus subjects are divided to 60% (mild), 30% (moderate), and 10% (severe). While TFI questionnaire, 50% showed a (mild), 25% (moderate), and 25% showed (severe). We postulated a strong significant positive association between HADS and tinnitus severity: THI (P=0.000) and TFI (P= 0.001). Those data revealed that tinnitus perception has negative impacts on QoL, and the severity may be altered by laterality.

ABSTRACT

OBJECTIVES: To investigate the association among hypertension, tinnitus, and sensorineural hearing loss and evaluate the influence of other covariates on this association. METHODS: Baseline data (2008-2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were analyzed. Altogether, 900 participants were evaluated. The baseline assessment consisted of a 7-hour examination to obtain clinical and laboratory variables. Hearing was measured using pure-tone audiometry. RESULTS: Overall, 33.3% of the participants had hypertension. Participants with hypertension were more likely to be older, male, and diabetic compared to those without hypertension. The prevalence of tinnitus was higher among hypertensive participants and the odds ratio for tinnitus was higher in participants with hypertension than in those without hypertension. However, the difference was not significant after adjusting for age. Audiometric results at 250-8,000 Hz were worse in participants with hypertension than in those without hypertension in the crude analysis; however, the differences were not significant after adjustment for age, sex, diagnosis of diabetes, and exposure to noise. No significant difference was observed in hearing thresholds among participants having hypertension for <6 years, those having hypertension for ≥6 years, and individuals without hypertension. CONCLUSION: Hearing thresholds were worse in participants with hypertension. However, after adjusting for age, sex, diagnosis of diabetes, and exposure to noise, no significant differences were observed between participants with and without hypertension. A higher prevalence of tinnitus was observed in participants with hypertension compared to those without hypertension, but without significance after adjusting for age.

ABSTRACT

Non-steady state noise has become the main type of workplace noise. Compared with steady state noise, non-steady state noise may cause more serious hearing loss. This paper reviews the new situation of occupational hearing loss caused by non-steady state noise exposure, the overview of international noise exposure assessment standards and new challenges, and the new evidence of non-steady state noise induced hearing loss, so as to provide the basis for the future research of non-steady state noise induced hearing loss.

ABSTRACT

RESUMO Objetivo Avaliar a audibilidade de fala em crianças usuárias de próteses auditivas e correlacionar o Índice de Inteligibilidade de Fala à detecção de fonemas. Método 22 crianças e adolescentes usuários de próteses auditivas passaram por avaliação audiológica básica, verificação in situ (e consequente obtenção do Índice de Inteligibilidade de Fala - SII - para condições com e sem próteses auditivas) e pesquisa dos limiares de detecção para fonemas por meio do teste Ling-6(HL). Resultados O SII médio foi 25,1 sem próteses auditivas e 68,9 com amplificação (p <0,001*). Os limiares de detecção de fonemas em campo livre, em dBNA, foram, sem amplificação /m/=29,9, /u/=29,5, /a/=35,5, /i/=30,8, /∫/=44,2 e /s/=44,9, e com amplificação /m/=13,0, /u/=11,5 /a/=14,3, /i/=15,4, /∫/=20,4 e /s/=23,1 (p <0,001*). Houve correlação negativa entre SII e os limiares de todos os fonemas na condição sem próteses (p≤0,001*) e entre SII e o limiar do /s/ com próteses (p = 0,036*). Conclusão Os limiares de detecção de todos os fonemas são menores do que na condição sem próteses. Há correlação negativa entre SII e os limiares de todos os fonemas na situação sem próteses e entre SII e o limiar de detecção do fonema /s/ na situação com próteses auditivas.


ABSTRACT Purpose To evaluate speech audibility in schoolchildren hearing aids users and correlate the Speech Intelligibility Index to phonemes detecion. Methods 22 children and adolescents hearing aids users, underwent audiological evaluation, in situ verification (and consequent obtaining the Speech Intelligibility Index - SII - for conditions with and without hearing aids) and detection thresholds for phonemes by Ling-6 (HL) test. Results The average value for the SII was 25.1 without hearing aids and 68.9 with amplification (p <0.001 *). The phoneme detection thresholds in free field, in dBHL, were, without amplification /m/ = 29.9, /u/ = 29.5, /a/ = 35.5, /i/ = 30.8, /∫/ = 44.2 e /s/ = 44.9, and with amplification /m/ = 13.0, /u/ = 11.5 /a/ = 14.3, /i/ = 15.4, /∫/ = 20.4 e /s/ = 23.1 (p<0.001*). There was a negative correlation between SII and the thresholds of all phonemes in the condition without hearing aids (p≤0.001*) and between SII and the /s/ threshold with hearing aids (p = 0.036*). Conclusion The detection thresholds for all phonemes are lower than without hearing aids. There is a negative correlation between SII and the thresholds of all phonemes in the situation without hearing aids and between SII and the detection threshold of the phoneme / s / in the situation with hearing aids.

ABSTRACT

RESUMO Objetivo Avaliar a função coclear de trabalhadores marítimos Offshore e Onshore de uma empresa naval da cidade do Rio de Janeiro e estimar a magnitude de associação entre a exposição ocupacional ao ruído e/ou substâncias químicas e alterações na função coclear. Método Neste estudo, foram avaliados trabalhadores marítimos entre 20-49 anos, de ambos os gêneros, sem queixas auditivas, distribuídos em dois grupos: o Grupo Offshore, que operam em alto mar com exposição ocupacional; e o Grupo Onshore, que operam em escritórios sem exposição ocupacional. Para avaliação da função coclear, foram realizados os exames de emissões otoacústicas evocadas por estímulo transiente (EOAT) e por produto de distorção (EOAPD). Resultados As respostas das EOAT e EOAPD foram, em média, menores no Grupo Offshore, para todas as frequências analisadas. A proporção de falhas observadas também foi maior no grupo de exposição (Offshore), tanto no critério geral quanto por frequência específica, principalmente para as frequências mais agudas de cada teste, 4 kHz para EOAT e 6 kHz para EOAPD. Conclusão Os resultados sugerem que a exposição a ruído e/ou a substâncias químicas pode contribuir significativamente para alterações da função coclear de trabalhadores marítimos, mesmo antes de manifestarem queixas auditivas.


ABSTRACT Purpose To evaluate the cochlear function of offshore and onshore seafaring workers of a naval company in the city of Rio de Janeiro and to estimate the degree of association between occupational exposure to noise and/or chemical substances and alteration in cochlear function. Methods This study evaluated seafaring workers aged 20 to 49, of both genders, without auditory symptoms, divided into two groups: the Offshore Group, operating in the high seas with occupational exposure; and the Onshore Group, operating in offices without occupational exposure. Exams were performed to evaluate cochlear function, including transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE). Results The TEOAE and DPOAE responses were on average lower in the Offshore Group, for all frequencies analyzed. The proportion of failures observed was also higher in the exposure group (Offshore), for general response and specific frequency, mainly for the frequencies of 4 kHz for TEOAE and 6 kHz for DPOAE. Conclusion The results suggest that exposure to noise and/or chemical substances can contribute to alterations in cochlear function in seafarers even without manifesting auditory symptoms.

Não houve diferença nos resultados com os indivíduos utilizando o Sistema Ponto® com a banda elástica e após a cirurgia. Conclusão O Sistema Ponto® propiciou benefício nas habilidades auditivas de detecção em todas as frequências testadas, assim como no reconhecimento de sentenças no silêncio e no ruído.


ABSTRACT Purpose To describe the benefits in hearing thresholds and sentence recognition performance in silence and noise, in users of the unilateral Ponto® system. Methods An observational, retrospective, longitudinal study. The sample consisted of secondary data sources from 10 individuals with conductive or mixed hearing loss who underwent surgery with the Ponto® System. The results were analyzed in the following pre-surgical conditions (without hearing aids; with hearing aids by air or bone conduction; with the Ponto Pro® processor with a soft band) and post-surgical (on activation and after six months of use). Results The thresholds of pure tone audiometry by air and bone conductions remained stable after surgery, while the auditory thresholds in free field and speech recognition in silence and in noise were statistically better when using the Ponto® system. There was no difference between the results obtained with the individuals using Ponto® with soft band and post-surgically. Conclusion The Ponto® system provided benefits in hearing detection skills in all tested frequencies, as well as, in recognition of the sentence in silence and noise.

ABSTRACT

Abstract Introduction: Acute otitis media is a disease with high global prevalence, that can lead to several acute complications and auditory sequelae. Data regarding the auditory evaluation in the acute phase of acute otitis media are scarce. Objective: To evaluate the main audiometric changes (air and bone conduction thresholds) in the initial phase of an acute otitis media episode. Methods: A case-control study was performed. Patients diagnosed with acute otitis media with less than 7 days of evolution in relation to the complaint onset were selected, and healthy volunteers were selected as controls. The acute otitis media and control groups were submitted to pure tone and vocal audiometry. Results: The acute otitis media group included a total of 27 patients (30 ears). Hearing loss was present in 90.0% of the ears with acute otitis media, with conductive loss in 14 (46.67%) and mixed loss in 13 (43.33%). Both the air and bone conduction thresholds obtained with the tonal audiometry in the acute otitis media group were significantly worse than the controls at all tested frequencies (p< 0.05). In patients with acute otitis media, we observed that the thresholds for frequency >1 kHz (bone conduction) and 3 kHz (air conduction) were significantly worse in patients with tinnitus compared to patients without tinnitus. Conclusion: During the first 7 days of evolution after the onset of an isolated episode of acute otitis media, we observed significant increases in bone and air thresholds at all frequencies, especially >2 kHz, compared to healthy ears.


Resumo Introdução: A otite média aguda é uma doença de elevada incidência global, que pode levar a diversas complicações agudas e sequelas auditivas. Dados referentes à avaliação auditiva na fase aguda da otite média aguda são escassos. Objetivo: Avaliar as principais alterações audiométricas (limiares em via aérea e óssea) na fase inicial de um episódio de otite média aguda. Método: Realizou-se estudo de caso-controle. Selecionamos pacientes com diagnóstico de otite média aguda, com menos de sete dias de evolução em relação ao início das queixas, e voluntários saudáveis foram selecionados como controles. Os grupos otite média aguda e controle foram submetidos a audiometria tonal, vocal e audiometria. Resultados: O grupo otite média aguda incluiu 27 pacientes (30 orelhas). Observou-se presença de perda auditiva em 90% das orelhas com otite média aguda, condutiva em 14 (46,67%) e mista em 13 (43,33%). Tanto os limiares auditivos por via aérea quanto os limiares por via óssea obtidos com audiometria tonal do grupo otite média aguda eram significativamente piores em relação aos controles, em todas as frequências testadas (p < 0,05). Em pacientes com otite média aguda, observamos que os limiares das frequências acima de 1 kHz (via óssea) e 3 kHz (via aérea) eram significantemente piores entre pacientes com zumbido em comparação a pacientes sem zumbido. Conclusão: Nos primeiros sete dias de evolução do quadro inicial de um episódio isolado de otite média aguda, observamos aumentos significativos dos limiares ósseos e aéreos em todas as frequências, principalmente nas acima de 2 kHz, em comparação a orelhas sadias.

ABSTRACT

Abstract Introduction: Hearing acuity, central auditory processing and cognition contribute to the speech recognition difficulty experienced by older adults. Therefore, quantifying the contribution of these factors on speech recognition problem is important in order to formulate a holistic and effective rehabilitation. Objective: To examine the relative contributions of auditory functioning and cognition status to speech recognition in quiet and in noise. Methods: We measured speech recognition in quiet and in composite noise using the Malay Hearing in noise test on 72 native Malay speakers (60-82 years) older adults with normal to mild hearing loss. Auditory function included pure tone audiogram, gaps-in-noise, and dichotic digit tests. Cognitive function was assessed using the Malay Montreal cognitive assessment. Results: Linear regression analyses using backward elimination technique revealed that had the better ear four frequency average (0.5-4 kHz) (4FA), high frequency average and Malay Montreal cognitive assessment attributed to speech perception in quiet (total r2 = 0.499). On the other hand, high frequency average, Malay Montreal cognitive assessment and dichotic digit tests contributed significantly to speech recognition in noise (total r2 = 0.307). Whereas the better ear high frequency average primarily measured the speech recognition in quiet, the speech recognition in noise was mainly measured by cognitive function. Conclusions: These findings highlight the fact that besides hearing sensitivity, cognition plays an important role in speech recognition ability among older adults, especially in noisy environments. Therefore, in addition to hearing aids, rehabilitation, which trains cognition, may have a role in improving speech recognition in noise ability of older adults.


Resumo Introdução: A alteração da acuidade auditiva, do processamento auditivo central e da cognição são fatores que contribuem para a dificuldade de reconhecimento da fala em idosos. Portanto, quantificar a contribuição desses fatores no problema de reconhecimento da fala é importante para a formulação de uma reabilitação holística e efetiva. Objetivo: Examinar as contribuições relativas do funcionamento auditivo e do estado cognitivo para o reconhecimento da fala no silêncio e no ruído. Método: Nós medimos o reconhecimento de fala no silêncio e no ruído composto com o teste Malay hearing in noise test em 72 idosos malaios nativos falantes (60-82 anos) com audição normal a perda auditiva de grau leve. A avaliação da função auditiva incluiu audiograma de tons puros, teste gaps-in-noise e testes dicótico de dígitos. A função cognitiva foi avaliada pelo teste Malay Montreal cognitive assessment. Resultados: Análises de regressão linear com técnicas de eliminação backward na orelha melhor revelaram média de quatro frequências (0,5-4 kHz) (4AF), média de alta frequência e teste Malay Montreal cognitive assessment na orelha melhor, mensurada pela percepção da fala no silêncio (r2 total = 0,499). Por outro lado, a média de alta frequência, Malay Montreal cognitive assessment e o teste dicótico de dígitos contribuíram significativamente para o reconhecimento da fala no ruído (r2 total = 0,307). Enquanto a média de alta frequência da melhor orelha mediu principalmente o reconhecimento da fala no silêncio, o reconhecimento da fala no ruído foi mensurado principalmente pela função cognitiva. Conclusões: Esses achados destacam o fato de que, além da sensibilidade auditiva, a cognição desempenha um papel importante na capacidade de reconhecimento da fala em idosos, principalmente em ambientes ruidosos. Portanto, além de aparelhos auditivos, a reabilitação, que treina a cognição, pode ter um papel na melhoria da capacidade do reconhecimento da fala no ruído entre os idosos.

ABSTRACT

Abstract Introduction Spinocerebellar ataxia (SCA) is part of a genetic and clinical heteroge- neous group of neurodegenerative diseases characterized by progressive cerebellar ataxia. Objective To describe the results of audiological and electrophysiological hearing evaluations in patients with sporadic ataxia (SA). Methods A retrospective cross-sectional study was carried out with 11 patients submitted to the following procedures: anamnesis, otorhinolaryngological evaluation, tonal and vocal audiometry, acoustic immittance and brainstem auditory evoked potential (BAEP) tests. Results The patients presented with a prevalence of gait imbalance, of dysarthria, and of dysphagia; in the audiometric and BAEPs, four patients presented with alterations; in the acoustic immittance test, five patients presented with alterations, predominantly bilateral. Conclusion The most evident alterations in the audiological evaluation were the prevalence of the descending audiometric configuration between the frequencies of 2 and 4 kHz and the absence of the acoustic reflex between the frequencies of 3 and 4 kHz bilaterally. In the electrophysiological evaluation, the patients presented changes with a prevalence of increased I, III and V wave latencies and the interval in the interpeak I-III, I-V and III-V. In the present study, it was observed that auditory complaints did not have a significant prevalence in this type of ataxia, which does not occur in some types of autosomal recessive and dominant ataxia.

ABSTRACT

Abstract Introduction Patient-reported outcome measures, inventory and or questionnaire, allow patients to present their perspective of the impact of their individual condition on a day-to-day basis, independent of the analysis of test results by the expert clinician. Outcome measures are recommended when there is evidence showing their reliability, validity and sensitivity. There are standardized patient-reported outcome measures for hearing in English language; however, other languages lack these instruments. Objective Adapt the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese and analyze its validation measures. Methods We conducted two studies. In Study 1, we translated and adapted the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese according to good practice guidelines; this included the pre-test stage. In Study 2, we administered the Portuguese version to adults with and without hearing loss (n = 31 and 18, respectively) and analyzed the measures of instrument validation, reliability, and reproducibility. Moreover, we calculated the correlation between pure tone thresholds and scores on the questionnaire. Results The results obtained in Study 1 demonstrated the feasibility of the translation process and the instrument's cultural adaptation, as well as its applicability, resulting in the Portuguese version of the Amsterdam inventory for auditory disability and handicap. In Study 2, the results revealed construct values for the questions and domains, as well as for the total reliable score. The intra-interviewer test-retest condition showed excellent reproducibility (ICC = 0.97). Finally, there was a strong positive correlation (r = 0.83) between the mean pure tone threshold and the hearing difficulties values, as measured by the instrument's scores. Conclusion The English version of the Amsterdam inventory for auditory disability and handicap could be translated and adapted to Brazilian Portuguese. An analyses of the validation process yielded reliable, consistent, and stable results.


Resumo Introdução Medidas de resultados relatados pelo paciente, inventários e/ou questionários, permitem que os pacientes apresentem suas perspectivas do impacto de sua condição no dia a dia, independentemente da análise dos resultados dos testes realizados pelo especialista. Esses instrumentos são recomendados quando há evidências que mostram sua confiabilidade, validade e sensibilidade. Existem medidas de resultados relatados pelo paciente padronizadas para a audição em língua inglesa; no entanto, esses instrumentos não existem em outras línguas. Objetivo Adaptar o Amsterdam inventory for auditory disability and handicap para o português brasileiro e avaliar suas medidas de validação. Método Realizamos dois estudos. No estudo 1, traduzimos e adaptamos o Amsterdam inventory for auditory disability and handicap para o português brasileiro de acordo com as diretrizes de boas práticas; inclusive a fase de pré-teste. No estudo 2, aplicamos a versão em português em adultos com e sem perda auditiva (n = 31 e 18, respectivamente) e analisamos as medidas de validação, confiabilidade e reprodutibilidade do instrumento.

ABSTRACT

ABSTRACT Objective To analyze the latency and the amplitude values of Mismatch Negativity and P300 cognitive potential in children with stuttering, with no auditory complaints, with auditory thresholds within the normality range, comparing them to the findings of a Control Group. Methods A cross-sectional study involving 50 children of both sexes, 15 with stuttering and 35 without stuttering, aged 6 to 11 years, with no diagnosis of ear pathology or other diseases. All children were submitted to peripheral audiological evaluation (meatoscopy, pure tone testing, speech audiometry, and acoustic immittance measures) and a central audiological evaluation (investigation of the Mismatch Negativity and P300 cognitive potential). For the evaluation of fluency, all children with stuttering had a specific history taken and were video recorded in a spontaneous speech. Afterwards, the transcription was done, followed by speech analysis to classify children according the severity of stuttering. Results There was a significant difference in the latencies of Mismatch Negativity and P300 cognitive potential, as well as in the amplitude of Mismatch Negativity. Conclusion There was a significant delay in the latencies of Mismatch Negativity and P300 cognitive potential, as well as increase in the amplitude of the Mismatch Negativity in children with stuttering when compared to children in the Control Group. Changes in the morphology of the waves were found in the Stuttering Group.


RESUMO Objetivo Analisar os valores de latência e amplitude do Mismatch Negativity e potencial cognitivo P300 em crianças com gagueira, sem queixas auditivas, com limiares auditivos dentro dos padrões de normalidade, comparando aos achados de um Grupo Controle. Métodos Estudo transversal, do qual participaram 50 crianças de ambos os sexos, sendo 15 com gagueira e 35 sem gagueira, entre 6 e 11 anos de idade, sem diagnóstico de patologias otológicas ou outras doenças. Todas as crianças realizaram avaliação audiológica periférica (meatoscopia, audiometria tonal, audiometria vocal e medidas de imitância acústica) e avaliação audiológica central (Mismatch Negativity e potencial cognitivo P300). Para avaliação da fluência, as crianças com gagueira realizaram anamnese específica, seguida da filmagem de uma fala espontânea, que foi transcrita e analisada quanto à severidade da gagueira. Resultados Houve diferença significativa nas latências do Mismatch Negativity e do potencial cognitivo P300, assim como na amplitude do Mismatch Negativity. Conclusão Verificou-se atraso nas latências do Mismatch Negativity e potencial cognitivo P300 nas crianças com gagueira, assim como aumento na amplitude do Mismatch Negativity, ao serem comparados com crianças do Grupo Controle. No Grupo com Gagueira foram igualmente identificadas alterações na morfologia das ondas.

ABSTRACT

RESUMO Objetivo Estabelecer relações entre o desempenho em tarefa de reconhecimento de palavras com e sem sentido e grau e configuração da perda auditiva, utilizando valores de Índices de Inteligibilidade de Fala (SII) como indicadores, em crianças com deficiência auditiva. Método Foram estabelecidos os SII para sons de entradas de 55 e 65 Decibéis Nível de Pressão Sonora (dBNPS) de dez crianças com perda auditiva neurossensorial usuárias de aparelho de amplificação sonora individual bilateralmente que têm a linguagem oral como principal modalidade de comunicação. As crianças foram submetidas à tarefa de repetição de palavras com e sem sentido em duas ou três diferentes intensidades. As emissões foram analisadas de acordo com o Protocolo Word Association for Syllable Perception (WASP). Na análise dos dados, o SII foi comparado com os resultados obtidos em cada critério de análise. Resultados Para o desempenho em palavras, houve diferença estatisticamente significante entre os dois tipos de estímulo em 55dBNPS. Para o desempenho em consoantes e ponto de articulação, houve diferença estatisticamente significante entre os tipos de estímulos em 65 e 55dBNPS e também entre as intensidades de 65 e 55 dBNPS nas palavras sem sentido. Conclusão De modo geral, não houve regularidade na relação entre capacidade auditiva e desempenho em tarefas de percepção da fala. Os resultados sugerem que o desempenho nas tarefas de reconhecimento de palavras sem sentido tem maior relação com o índice de inteligibilidade do que as palavras com sentido, possivelmente por limitar as estratégias de fechamento semântico pelo sujeito.


ABSTRACT Purpose To establish the relationship between the performance on word recognition tasks, using words with and without sense and degree, and the configuration of hearing loss, by using Speech Inteligibility Index (SII) values as indicators, in children with hearing loss. Methods SII were established for 55 and 65 Decibel of Sound Pressure Level (dB SPL) input sounds of ten children presenting bilateral sensorineural hearing loss (SNHL), adapted with bilateral hearing aids, and who have oral language as the main mode of communication. The children were submitted to a word and nonsense-word repetition task of two or three intensity degrees. Their productions were analyzed according to the Word Association for Syllable Perception (WASP) Protocol. In the data analysis, the values of SII were compared with the results obtained in each analysis criterion. Results Pertaining to the words, there was statistically significant difference between the two types of stimuli in 55 dBSPL. As for the performance of consonants and point of articulation, there was a statistically significant difference between stimuli types in 65 and 55 dB SPL, and between intensities 65 and 55 dB SPL in nonsense words. Conclusion Overall, there was no regularity in the relationship between hearing ability and performance in speech perception tasks. The results suggest that performance in the nonsense words recognition tasks was more related to intelligibility index than to words with meaning, possibly because it limits semantic closure strategies by the subject.

ABSTRACT

OBJECTIVES: Human immunodeficiency virus-positive (HIV+) individuals can experience a decrease in antioxidants. Such deficiency can make inner ear cells and synapses more vulnerable to oxidative stress, resulting in auditory alterations, even in the presence of normal thresholds. This study aims to compare the audiological findings of HIV+ patients (with and without exposure to anti-retroviral treatment) to those of healthy individuals. METHODS: This was a cross-sectional observational study, comprising 42 normal-hearing adults divided into the Control Group (CG), without HIV; Group I (GI), HIV+, without exposure to the highly active anti-retroviral therapy (HAART); Group II (GII), HIV+, with exposure to HAART. All participants underwent conventional audiometry (0.25-8 kHz), high-frequency audiometry (9-20 kHz), transient evoked otoacoustic emissions (TEOAEs), efferent auditory pathway's inhibitory effect assessment, brainstem auditory evoked potentials (BAEPs), and cognitive potential (P300). RESULTS: In the comparison of the hearing thresholds between the groups, there was a statistically significant difference for most of the frequencies assessed (GII presented hearing thresholds significantly poor when compared with other groups). The presence of TEOAE and the inhibitory effect was also verified in a significantly higher number of individuals in the CG than in the other groups. As for the BAEP, there was a statistically significant difference for the interpeak intervals I-V (GII showed higher values when compared with CG). For P300, there were no statistically significant differences. CONCLUSION: Normal-hearing HIV+ individuals (with and without exposure to HAART) presented with poor performance in the audiological procedures, suggesting the presence of auditory alterations even in the presence of normal-hearing thresholds.

ABSTRACT

RESUMO Objetivo Investigar a percepção auditiva temporal, a orientação e a mobilidade de deficientes visuais. Métodos Estudo exploratório de intervenção, com amostra de conveniência composta por nove sujeitos cegos ou com baixa visão, com idades entre 23 e 64 anos, usuários de cão-guia e que realizaram os seguintes procedimentos: avaliação funcional de orientação e mobilidade, avaliação audiológica básica (audiometria tonal limiar, pesquisa do índice de reconhecimento de fala), avaliação do processamento auditivo temporal (teste de resolução temporal (random gap detection test - RGDT), teste de padrão de frequência (TPF), teste dicótico de dígitos (TDD), teste rápido de sentenças no ruído (TRIS). Resultados Todos os sujeitos apresentavam limiar audiométrico de grau normal, porém, um deles apresentava curva audiométrica do tipo neurossensorial e configuração descendente, sugerindo perda auditiva relacionada à idade. A avaliação das habilidades auditivas temporais mostrou valores dentro dos padrões de normalidade para todos os sujeitos, com exceção do teste RGDT, em que os sujeitos apresentaram valores menores (3,5 a 7,5 ms) do que os esperados para população de adultos com visão e audição normais. A avaliação da OM mostrou que todos os sujeitos necessitavam de adaptações técnicas, pois falhas foram observadas no percurso por eles executado. Conclusão A percepção auditiva temporal dos sujeitos deste estudo está adequada e a avaliação da OM mostra falhas que necessitam ser corrigidas.


ABSTRACT Purpose To investigate the temporal auditory perception, and OM of visually impaired people. Methods This is an exploratory intervention study including a convenience sample composed of nine blind or low vision subjects, aged between 23 and 64 years, guide dog users and who performed the following procedures: functional evaluation of OM, basic audiological evaluation (Pure tone audiometry, speech recognition index), temporal auditory processing assessment (random gap detection test (RGDT), frequency pattern test (FPT), dichotic digit Test (DDT), quick speech-in-noise test (QuickSIN). Results Although all subjects had normal-level audiometric thresholds, one subject had a sensorineural audiometric curve and descending configuration, suggesting an age-related hearing loss. Evaluation of the temporal auditory processing showed values within the normal for all subjects, except for the RGDT, in which test subjects had lower (3.5 to 7.5 ms.) than the expected values for the adult population with normal vision and hearing. Evaluation of OM showed that all subjects require technical adjustments as problems were observed in the route taken. Conclusion The temporal auditory processing of these subjects is appropriate and the evaluation of OM shows flaws that need to be corrected.

ABSTRACT

RESUMO Objetivo Correlacionar o desempenho de usuários de implante coclear unilateral em testes de reconhecimento de fala, no silêncio e no ruído, com as respostas ao questionário de autoavaliação Hearing Implant Sound Quality Index (HISQUI19) e correlacionar o desempenho em testes de reconhecimento de fala com o tempo de uso do dispositivo e a orelha implantada. Métodos Participaram 27 usuários de implante coclear unilateral com deficiência auditiva pós-lingual, que faziam uso do dispositivo há, pelo menos, um ano e apresentavam limiar tonal em campo livre menor que 40 dBA. Todos os participantes foram submetidos à audiometria tonal em campo livre, responderam ao questionário HISQUI19 e realizaram testes de reconhecimento de fala no silêncio e no ruído. Resultados As respostas ao questionário foram comparadas com os testes de reconhecimento de fala no silêncio e no ruído e não houve diferença estatisticamente significativa. Na comparação em relação ao tempo de uso do implante coclear, só houve diferença estatisticamente significativa para o teste de reconhecimento de fala no silêncio. Não houve correlação significativa entre o reconhecimento de fala e a orelha implantada. Conclusão independentemente do tempo de uso do dispositivo e/ou do desempenho nos testes de reconhecimento de fala, muitos participantes classificaram a qualidade sonora do implante coclear como moderada. A aplicação de testes que possibilitem mensurar a satisfação e o benefício dos usuários deve fazer parte da rotina clínica dos centros de implante.


ABSTRACT Purpose To correlate the performance of unilateral cochlear implant users in speech recognition tests, in quiet and noise, with the answers to the Hearing Implant Sound Quality Index (HISQUI19) self-assessment questionnaire; also, to correlate the performance in speech recognition tests with the time of CI use and the implanted ear. Methods A total of 27 unilateral CI users with postlingual hearing loss, who had been using the device for at least one year and had free-field pure-tone threshold lower than 40 dBA, participated in the study. All the participants were submitted to free-field pure-tone audiometry, answered the HISQUI19 questionnaire, and took speech recognition tests in quiet and noise. Results The answers to the questionnaire were compared with the speech recognition tests in quiet and noise; there was no statistically significant difference. When comparing with the time of CI use, there was a statistically significant difference only for the speech recognition test in quiet. There was no significant correlation between speech recognition and the implanted ear. Conclusion Regardless of the time of CI use and/or performance in the speech recognition tests, many participants classified the sound quality of their cochlear implant as moderate. Administering tests to measure the users' level of satisfaction and benefit should integrate the clinical routine in implantation centers.

ABSTRACT

RESUMO Objetivo Analisar as emissões otoacústicas evocadas produto de distorção (EOAPD) de indivíduos adultos entre 18 e 50 anos, com audição normal, e associar os resultados com os achados à timpanometria. Métodos Foram selecionados 27 prontuários de adultos com audição dentro dos padrões de normalidade, sem queixa auditiva, com curva timpanométrica do tipo A, Ad ou Ar, presença de reflexos acústicos, sem queixa de zumbido e de exposição frequente a níveis de pressão sonora elevados, com repouso auditivo mínimo de 14 horas no momento do exame e que realizaram o exame de emissões otoacústicas evocadas produto de distorção. Os resultados do exame de emissões otoacústicas foram analisados considerando os resultados das curvas timpanométricas apresentadas por estes indivíduos. Para análise dos dados foram aplicados testes não paramétricos e o nível de significância foi de 5%. Resultados foram analisados os resultados das emissões otoacústicas de 54 orelhas. Observou-se maior ocorrência da curva do tipo A em indivíduos sem queixas auditivas. Independente do lado, a maioria das orelhas que apresentou resposta presente ao exame de EOAPD, apresentou, também, curva timpanométrica normal. Observou-se correlação positiva entre a amplitude das EOAPD e o volume da orelha média para as frequências de 6000 Hz e uma tendência à significância em 4000 Hz Conclusão Foi possível concluir que há maior ocorrência de emissões otoacústicas presentes em indivíduos com audição normal e curva timpanométrica do tipo A e que a amplitude das EOAPD em 6000 Hz mostra-se menor nos indivíduos com audição normal e curva timpanométrica do tipo Ar ou Ad.


ABSTRACT Purpose To analyze distortion product evoked otoacoustic emissions in normal-hearing adults aged between 18 and 50 years old, and to associate the results with the findings of tympanometry. Methods 27 medical records were selected of adults with the following conditions: normal hearing; without auditory complaint; with type A, Ad or Ar tympanometric curve; with presence of acoustic reflexes; with no complaint of tinnitus or frequent exposure to high sound pressure levels; with minimal auditory rest of 14 hours at the time of the test, and who had undergone distortion product evoked otoacoustic emission (DPOAE) testing. The results of otoacoustic emissions were analyzed considering the results of the tympanometric curves presented by these individuals. For the data analysis, non-parametric tests were applied, and the level of significance was 5%. Results The results of otoacoustic emissions of 54 ears were analyzed. There was a greater occurrence of the type A curve in individuals without auditory complaints. Regardless of side, most ears whose response was present in the DPOAE test also presented normal tympanometric curve. There was a positive correlation between DPOAE amplitude and middle ear volume for the 6000Hz frequencies (p = 0.048) and a tendency to significance at 4000Hz (p = 0.054). Conclusion There was a higher occurrence of otoacoustic emissions present in normal-hearing individuals and type A tympanometric curve, and the amplitude of DPOAE at 6000Hz was smaller in normal-hearing individuals and type Ar or Ad tympanometric curve.

ABSTRACT

RESUMO Objetivo avaliar a influência da variável sexo nos valores da latência e amplitude da onda V do potencial evocado auditivo de tronco encefálico, com diferentes estímulos em neonatos. Métodos participaram deste estudo 62 neonatos nascidos a termo (29 do sexo feminino e 33 do sexo masculino). Realizou-se a pesquisa de limiar eletrofisiológico do potencial evocado auditivo de tronco encefálico com quatro estímulos diferentes (clique, Ichirp banda larga-BL, tone burst e Ichirp-frequência específica-FE), nas intensidades de 60, 40 e 20 dBnNA. A variável sexo foi comparada para cada estímulo e intensidade. Resultados os resultados obtidos demonstraram menor latência e maior amplitude no sexo feminino para o estímulo clique. Entretanto, para o estímulo tone burst, o sexo feminino apresentou maior latência e maior amplitude. Quando utilizados os estímulos Ichirp-BL e Ichirp-FE, a variável sexo não apresentou diferença estatisticamente significativa para os valores de latência e amplitude. Conclusão a onda V do PEATE de neonatos sofre influência da variável sexo, quando utilizados os estímulos clique e tone burst. Entretanto, não houve tal influência quando utilizado o estímulo Ichirp banda larga-BL e o estímulo Ichirp frequência específica-FE.


ABSTRACT Purpose To evaluate the influence of gender on the brainstem auditory evoked potentials V-wave latency and amplitude values in newborns, with different stimuli. Methods 62 full-term newborns (29 females and 33 males) participated in this study. The electrophysiological threshold of the brainstem auditory evoked potential was investigated with four different stimuli - click, broadband (BB) Ichirp, tone-burst, and specific-frequency (SF) Ichirp -, in intensities of 60, 40 and 20 dBnHL. The genders were compared in each stimulus and intensity. Results The results obtained showed lower latency and greater amplitude in females for the click stimulus. However, for tone-burst, the females presented higher latency and greater amplitude. When the BB-Ichirp and SF-Ichirp stimuli were used, the gender did not present a statistically significant difference in the latency and amplitude values. Conclusion The BAEP V-wave in newborns is influenced by gender when the click and tone-burst stimuli are used. However, such influence was not noted when the BB-Ichirp and SF-Ichirp stimuli were used.

ABSTRACT

Introduction: Studies have reported that although speech perception in noise was unaltered with and without digital noise reduction (DNR), the annoyance toward noise measured by acceptable noise level (ANL) was significantly improved by DNR with the range between 2.5 and 4.5 dB. It is unclear whether a similar improvement would be observed in those individuals who have an ANL ≥ 14 dB (predictive of poor hearing aid user) often rejects their aid because of annoyance toward noise. Objectives: (a) To determine the effect of activation of DNR on the improvement in the aided ANL from low- and high-ANL groups; and (b) to predict the change in ANL when DNR was activated. Method: Ten bilateral mild to severe sloping sensorineural hearing loss (SNHL) participants in each of the low- and high-ANL groups were involved. These participants were bilaterally fitted with receiver in canal (RIC) hearing aids (Oticon, Smorum, Egedal, Denmark) with a DNR processor. Both SNR-50% (Signal to noise ratio (in dB) required to achieve 50 % speech recognition) and ANL were assessed in DNR-on and DNR-off listening conditions. Results: Digital noise reduction has no effect on SNR-50 in each group. The annoyance level was significantly reduced in the DNR-on than DNR-off condition in the low-ANL group. In the high-ANL group, a strong negative correlation was observed between the ANL in DNR off and a change in ANL after DNR was employed in the hearing aid (benefit). The benefit of DNR on annoyance can be effectively predicted by baseline-aided ANL by linear regression. Conclusion: Digital noise reduction reduced the annoyance level in the high-ANL group, and the amount of improvement was related to the baseline-aided ANL value (AU)
