ABSTRACT

Abstract Introduction Musicians have an advantage over non-musicians in detecting, perceiving, and processing nonverbal (i.e., environmental sounds, tones and others) and verbal sounds (i.e., consonant, vowel, phrases and others) as well as instrumental sounds. In contrast to the high skill of musicians, there is another group of people who are tone-deaf and have difficulty in distinguishing musical sounds or singing in tune. These sounds can originate in different ways, such as a musical instrument, orchestra, or the human voice. Objectives The objective of the present work is to study frequency-following responses (FFRs) in individuals who can sing in-tune and those who sing off-tune. Methods Electrophysiological responses were recorded in 37 individuals divided in two groups: (i) control group (CG) with professional musicians, and (ii) experimental group (EG) with non-musicians. Results There was homogeneity between the two groups regarding age and gender. The CG had more homogeneous responses in the latency of the FFRs waves when responses between the right and left ears were compared to those of the EG. Conclusions This study showed that monaural stimulation (right or left) in an FFR test is useful for demonstrating impairment of speech perception in individuals who sing off tune. The response of the left ear appears to present more subtlety and reliability when identifying the coding of speech sound in individuals who sing off tune.

ABSTRACT Purpose to describe which abilities of central auditory processing are more frequently related for the group of specialists to the performance of the speaker comparison test (CL), traditionally performed by forensic experts. Methods a prospective, descriptive study with quantitative and qualitative analysis and data were obtained through a consensus of experts. Five speech therapists participated in the meeting, two specialists in audiology (EA), two specialists in voice (VS), and an expert speech therapist (FP). The meeting was held virtually and synchronously, lasting 1 hour and 30 minutes. The tasks performed during the Speaker Comparison (LC) exam were considered from a protocol available in the literature. The AEs received explanations about each of the tasks and were asked to discuss which auditory processing skills (ACP) would be involved in the performance of each of them. Results seven PAC skills were considered in the experts' meeting as essential for the tasks performed in the CL exam. Temporal ordering was the most cited skill, being present in six tasks, and the speech material transcription task is the one that requires more skills from the PAC. Conclusion Seven PAC skills were considered in the experts' meeting as essential for the tasks performed in the CL exam. Temporal ordering was the most cited skill, being present in six tasks, and the speech material transcription task is the one that requires more skills from the PAC.

ABSTRACT

This text is the continuation of the XVIII SBFa Congress publication. In part "A" we presented the analyses on clinical vocal evaluation. Part "B" focuses on vocal rehabilitation: 4. Traditional techniques of vocal therapy; 5. Modern techniques of electrostimulation and photobiomodulation applied to vocal rehabilitation. The numerous studies on the various programs, methods, and techniques of traditional rehabilitation techniques, and many with high quality of evidence, allow us to consider such procedures relatively well described, safe, and with known effects, accounting for the treatment of various vocal disorders. The scientific evidence with traditional techniques is recognized worldwide. New fronts of evolution, with electrostimulation or photobiomodulation used to handle voice problems, seem to be promising as coadjutant approaches. There are more studies on electrostimulation in vocal rehabilitation than with photobiomodulation; however, scientific evidence for these two modern techniques is still limited. Knowledge and caution are required for the application of either technique.


O presente texto é a continuação da publicação referente ao XVIII Congresso da SBFa. Na parte "A" apresentamos análises sobre avaliação clínica vocal. O foco da parte "B" são aspectos de reabilitação vocal: 4. Técnicas tradicionais de terapia vocal; 5. Técnicas modernas de eletroestimulação e fotobiomodulação aplicadas à reabilitação. Os inúmeros estudos sobre os diversos programas, métodos ou técnicas tradicionais de reabilitação, muitos de elevada qualidade de evidência, permitem considerar tais procedimentos relativamente bem descritos, seguros e com efeitos conhecidos, dando conta do tratamento de diversos distúrbios vocais. As evidências científicas com as técnicas tradicionais são reconhecidas mundialmente. Novas frentes de evolução, como o uso da eletroestimulação ou fotobiomodulação em voz parecem ser promissoras como abordagens coadjuvantes. Há mais estudos sobre eletroestimulação em voz do que com fotobiomodulação, contudo, evidências científicas para essas duas técnicas modernas são ainda limitadas. Conhecimento e cautela são necessários para a aplicação de quaisquer técnicas.

ABSTRACT

During the XXVIII Brazilian Congress of SBFa, 24 specialists met and, from a leading position on scientific research as a tool for connecting laboratory and clinic, five fronts of knowledge of the voice specialty were discussed as following: Perceptual-auditory judgment of vocal quality; 2. Acoustic analysis of the vocal signal; 3. Voice self-assessment; 4. Traditional techniques of therapy; 5. Modern techniques of electrostimulation and photobiomodulation (PBMT) in voice. Part "a" of this publication was associated with the consolidation of the analyses of the first three aspects. The trend in the perceptual-auditory judgment of vocal quality was related to the use of standard protocols. The acoustic evaluation of the vocal signal is accessible and can be done descriptively or by extraction of parameters, thus preferring multiparametric measures. Finally, the analysis of the individual himself closes this triad of voice documentation, which will be the basis for the conclusion of the evaluation, reference for monitoring progress, and evaluation of treatment results.


No XXVIII Congresso Brasileiro da SBFa, 24 especialistas reuniram-se e, a partir de um posicionamento condutor sobre pesquisa científica como ferramenta de conexão entre laboratório e clínica, cinco frentes de conhecimento da especialidade de voz foram discutidas: 1. Julgamento perceptivo-auditivo da qualidade vocal; 2. Análise acústica do sinal vocal; 3. Autoavaliação em voz; 4. Técnicas tradicionais de terapia; 5. Técnicas modernas de eletroestimulação e fotobiomodulação em voz. A parte "a" desta publicação é a consolidação das análises dos três primeiros aspectos. A tendência no julgamento perceptivo-auditivo da qualidade vocal é o uso de protocolos padrão. A avaliação acústica do sinal vocal é acessível e pode ser feita de modo descritivo ou por extração de parâmetros, preferindo-se medidas multiparamétricas. Finalmente, a análise do próprio indivíduo fecha essa tríade de documentação fonoaudiológica, que será base para a conclusão da avaliação, referência para monitoramento do progresso e avaliação de resultado de tratamento.

ABSTRACT

RESUMO Objetivo Verificar se a estimulação das habilidades auditivas de fonoaudiólogos com e sem dificuldades no processamento auditivo central (PAC) interfere no desempenho da avaliação perceptivo-auditiva (APA) do desvio vocal predominante. Métodos Estudo prospectivo, quase-experimental, realizado com 26 fonoaudiólogos, desenvolvido em cinco etapas: Etapa1: Pré-intervenção - primeira APA, composta por 30 amostras da vogal sustentada /ε/, acrescidas de 20% de repetição (seis amostras repetidas), apresentadas randomicamente, na qual os participantes deveriam identificar o desvio vocal predominante; Etapa 2: Triagem das habilidades do PAC com nove testes da plataforma AudBility; Etapa 3: Treinamento perceptivo-auditivo do desvio vocal predominante e segunda APA, idêntica à anterior; Etapa 4: Intervenção - estimulação das habilidades auditivas (EHA), realizada por 14 fonoaudiólogos, sendo oito que não passaram na triagem da Etapa 2 (Grupo1) e seis que passaram na triagem e, espontaneamente, realizaram a EHA (Grupo G2a). Os outros 12 participantes não realizaram EHA e formaram o Grupo G2b; Etapa 5: Pós-intervenção - realização da terceira APA, idêntica às anteriores, por todos os fonoaudiólogos. A acurácia das respostas e confiabilidade intra-avaliadores foram verificadas ao longo das três APAs. Resultados Os três grupos apresentaram desempenhos semelhantes nas três APAs. G1 e G2a não apresentaram melhora no desempenho da análise do desvio vocal predominante pós-EHA. A confiabilidade intra-avaliador pré-intervenção no G1 foi inferior a do G2a e G2b nas APA1 e APA2, e similar a eles na APA3, pós-intervenção. Conclusão EHA proposto não impactou a acurácia da APA, mas influenciou a confiabilidade intra-avaliador dos fonoaudiólogos com dificuldades nas habilidades auditivas do PAC.


ABSTRACT Purpose To verify if the stimulation of auditory skills of speech therapists with and without difficulty in auditory processing (CAP) interferes in performance of auditory-perceptual assessment (APA) regarding predominant vocal deviation. Methods Prospective, quasi-experimental study, conducted with 26 speech therapists and developed in five stages: Stage1: Pre-intervention - APA, composed of 30 samples of sustained vowel emissions /ε/, plus 20% repetition (six repeated samples) in which participants should identify the predominant vocal deviation. Stage2: Screening of CAP skills through nine tests of AudBility web platform. Stage3: Perceptual-auditory training of predominant vocal deviation and, later, second APA, identical to previous one. Stage4: Intervention - Stimulation of auditory skills (EHA) performed by 14 participants, eight of which failed the screening from Stage2 and six who passed th e screening and spontaneously performed EHA (Group G2a ). The other 12 participants did not perform EHA and formed the G2b Group. Stage5: Post-intervention - Third execution of APA, identical to previous, by all participants. Accuracy of analysis and intra-rater reliability were assessed in all APAs. Results The three groups showed similar performances in the three APAs. G1 and G2a showed no improvement in the performance of the analysis of predominant vocal deviation after EHA. Pre-intervention intra-rater reliability in G1 was lower than in G2a and G2b in APA1 and APA2, and similar to them in APA3, post-intervention. Conclusion Proposed EHA had no impact on APA accuracy, but influenced in intra-rater reliability of speech therapists with difficulty in the hearing skills of CAP.

ABSTRACT

OBJECTIVE: To determine whether an association exists between auditory skills and the reliability of judgments of the vocal deviation grade and the degrees of roughness and breathiness and to evaluate whether these skills are predictive of interrater reliability in auditory-perceptual evaluations. METHODS: The sample consisted of 20 speech-language pathology students without previous training in auditory-perceptual evaluation. The students underwent a basic audiological evaluation and a central auditory processing evaluation. They then participated in two auditory-perceptual evaluation sessions assessing the general grade (GG) and the degrees of roughness and breathiness of 44 samples of sustained vowel production with the presence or absence of dysphonia. For statistical analysis, the intraclass correlation coefficient (ICC) and a beta regression model were used. RESULTS: A difference was found in the average ICCs of the GG parameter between listeners with high and low temporal resolution and binaural interaction skills. Temporal resolution skills and binaural interaction affected the ICC of listeners in the GG evaluation, reducing the likelihood of reliability by 2.8 and 3.6 times, respectively. CONCLUSION: An association exists between temporal resolution skills and binaural interaction and the reliability of listeners in evaluations of vocal deviation severity. Listeners with low levels of these skills show less reliability in evaluations of the severity of vocal deviation. In addition, temporal resolution and binaural interaction are predictors and explain 42.7% of the variability in the reliability of evaluations of vocal deviation severity.

ABSTRACT

PURPOSE: To verify the association between laryngopharyngeal reflux (LPR) with age, gender, vocal deviation and voice complaints. METHODS: The study included patients between 18 and 70 years old, referred to the Otorhinolaryngology service for complaints of voice or reflux, of both sexes. Endolaryngeal findings were classified using the Reflux Finding Score (RFS) scale. The presence or absence of vocal and reflux complaints was verified and correlated with the RFS classification. On the same date, they were submitted to sustained vowel voice recording and chained speech. The auditory-perceptual assessment was performed by a speech therapist, classifying the general degree of vocal deviation based on the GRBASI scale. RESULTS: Ninety-seven patients were evaluated, with a mean age of 42. 6 years, 62. 3% female, and mean RFS scores of 6. 26 points. Among the patients, 48 subjects had vocal complaints, 34 women with a mean age of 44. 9 years and an average RFS score of 6. 94 points. The other 49 individuals had no vocal complaints, and of these 27 were women, with a mean age of 41. 2 years and a mean RFS score of 5. 5 points. The variables "reflux complaint", "vocal complaint" and age were the ones that most correlated with the RFS scale scores. CONCLUSION: There is a relationship among reflux complaints, laryngeal findings and vocal complaint.


OBJETIVO: Verificar a associação entre Refluxo laringofaríngeo (RLF) com idade, sexo, desvio vocal e queixas de voz. MÉTODO: Participaram do estudo pacientes entre 18 e 70 anos, encaminhados ao serviço de otorrinolaringologia por queixas de voz ou refluxo, de ambos os sexos. Os achados endolaríngeos foram classificados utilizando a escala Reflux Finding Score (RFS). A presença ou não de queixas vocais e de refluxo foi verificada e correlacionada com a classificação RFS. Na mesma data, os pacientes foram submetidos à gravação de voz de vogal sustentada e fala encadeada. A avaliação perceptivo-auditiva foi realizada por uma fonoaudióloga, classificando o grau geral do desvio vocal com base na escala GRBASI. RESULTADOS: Foram avaliados 97 pacientes, com média de idade de 42,6 anos, sendo 62,3% do sexo feminino e média dos escores da escala RFS igual a 6,26 pontos. Do total de pacientes, 48 indivíduos apresentavam queixas vocais, sendo 34 mulheres com idade média de 44,9 anos e escore RFS médio de 6,94 pontos. Os outros 49 indivíduos não apresentavam queixas vocais, e desses 27 eram mulheres, com idade média de 41,2 anos e média de escore RFS igual a 5,5 pontos. As variáveis "queixa de refluxo", "queixa vocal" e idade foram as que mais se correlacionaram com os escores da escala RFS. CONCLUSÃO: Há relação entre queixas de refluxo, achados laríngeos e queixa vocal.

ABSTRACT

PURPOSE: To evaluate the ability that in tune and out of tune individuals have to identify normal and deviated voice qualities and to compare it with their performance in auditory processing tests and perceptual judgment. METHOD: The study investigated 15 in tune and 15 out of tune individuals. Participants were matched for age and sex, were amateur choir singers, had normal hearing thresholds and normal vocal quality. All individuals underwent Pitch-matching scanning to be classified as in or out of tune. Next, they performed the Pitch Pattern Sequence (PPS) and the Duration Pattern Sequence (DPS) tests and the perceptual judgment of 36 voices plus 20% of repetition for reliability analysis. RESULTS: The out of tune individuals had worse performance in the PPS and DPS for both ears (p=0.002 RE; p=0.001 LE; p=0.009 DPS); no difference was observed in the perceptual judgment and the reliability (p=0.153). However, participants with normal PPS and DPS had better performance in the perceptual judgment and better reliability (p=0.033). Thus, individuals with disorders in temporal auditory processing skills have greater difficulty in the perceptual judgment and have lower intra-rater reliability, despite being in or out of tune. CONCLUSION: It can be observed that voice tone is not required to guarantee good perceptual judgment. However, temporal patterns and intra-rater reliability are essential to perceptually assess normal and altered voice qualities. Therefore, auditory training should be included in programs that aim to develop voice perceptual judgment abilities.

ABSTRACT

RESUMO Objetivo: Avaliar a habilidade de identificação de vozes normais e alteradas por indivíduos afinados e desafinados, comparando seu desempenho nos testes de processamento auditivo e na avaliação perceptivo-auditiva. Método: Participaram 15 indivíduos afinados e 15 desafinados pareados quanto à idade e sexo, oriundos de um coral amador, com limiares auditivos e qualidade vocal dentro dos padrões de normalidade. Todos foram submetidos à Triagem da Afinação vocal para a alocação nos grupos de afinados e desafinados. Em seguida, realizaram o Teste Padrão de Frequência (TPF), Teste Padrão de Duração (TPD) e análise perceptivo-auditiva de 36 vozes, mais 20% de repetição para teste de confiabilidade. Resultados: Os indivíduos desafinados apresentaram resultados estatisticamente menores que os afinados no TPF e no TPD para ambas as orelhas (p=0,002 OD; p=0,001 OE; p=0,009 TPD). Resultados da análise perceptivo-auditiva e da confiabilidade não apresentaram diferença (p=0,153). Contudo, esses resultados foram melhores quando comparados os participantes com valores normais no TPF e TPD, em relação aos resultados alterados (p=0,033). Assim, participantes com testes temporais de processamento auditivo alterados apresentaram maiores dificuldades na análise perceptivo-auditiva e menor confiabilidade intrassujeito, independentemente de serem ou não afinados. Conclusão: Percebe-se que a afinação vocal não é um pré-requisito para a realização de uma boa avaliação perceptivo-auditiva da voz, mas os padrões temporais e a confiabilidade intrassujeito estão notavelmente associados à análise perceptivo-auditiva de vozes normais e alteradas. Assim, sugere-se que o treinamento auditivo seja contemplado em programas de desenvolvimento da habilidade de realizar avaliação perceptivo-auditiva da voz.

PURPOSE: To develop a game on vocal health and hygiene (VoxPedia) and apply it to adults aiming to investigate knowledge about vocal health and the vocal self-assessment in this population. METHODS: The study sample was composed of 293 adults, of which 204 were women and 129 were voice professionals, invited to participate through digital media. Participants completed to the following forms and instruments: 1) Informed Consent Form (ICF); 2) Identification Data form; 3) Voice Handicap Index: 10 (VHI-10) protocol; 4) Vocal Health and Hygiene Questionnaire (VHHQ); 5) VoxPedia quiz. RESULTS: The VoxPedia quiz was developed using simple and dynamic questions that allowed the participants to know their performance in real time. Data collected through this quiz showed that voice professionals reported reduced voice handicap and had higher scores in the VHHQ and VoxPedia. Voice professionals or not, participants who answered wrongly to the nature of impact of health aspects in the VHHQ reported increased voice handicap in the VHI-10; however, despite the self-reported handicap, most of them did not report voice complaints. In contrast, when voice complaints were reported, the participants not always perceived handicap or searched for vocal therapy. CONCLUSION: The VoxPedia quiz presented some concepts on vocal health and hygiene to the participants. In addition, it enabled the study of the relation between knowledge about vocal care and voice self-assessment. The data suggest that individuals with greater knowledge about vocal health and hygiene show better voice self-assessment, those with worse voice self-assessment do not perceive voice problems, and those who perceive voice problems do not necessarily seek professional assistance.


OBJETIVO: Desenvolver um game sobre saúde e higiene vocal (VoxPedia) e aplicá-lo em adultos, para investigar o conhecimento em cuidados vocais e compreender a autoavaliação vocal dos respondentes. MÉTODO: Participaram 293 adultos, 204 mulheres e 129 profissionais da voz, convidados através de mídias digitais. Os participantes responderam: 1) Termo de Consentimento Livre e Esclarecido (TCLE); 2) Dados de Identificação; 3) Protocolo do Índice de Desvantagem Vocal (IDV-10); 4) Questionário de Saúde e Higiene Vocal (QSHV); 5) Aplicação do quiz VoxPedia. RESULTADOS: O VoxPedia foi desenvolvido com questões simples e com dinâmica que permitiu aos participantes conhecerem seu desempenho em tempo real. Os dados adquiridos através do quiz mostram que os profissionais da voz relataram menos desvantagem vocal e acertaram mais itens no QSHV e questões do VoxPedia. Profissionais da voz ou não, os participantes que erraram a natureza do impacto dos aspectos de saúde no QSHV referiram maior desvantagem vocal no IDV-10. Contudo, apesar da desvantagem autorreferida, a maioria não relata problemas de voz. Em contrapartida, quando o respondente relatou problemas de voz, nem sempre houve desvantagem percebida ou busca por terapia vocal. CONCLUSÃO: O VoxPedia apresentou alguns conceitos de saúde e higiene vocal aos participantes. Além disso, possibilitou o estudo das relações entre conhecimento em cuidados vocais e autoavaliação vocal. Os dados sugerem que os indivíduos com mais conhecimento em cuidados vocais têm melhor autoavaliação de voz; participantes com pior autoavaliação vocal não percebem problemas de voz; e aqueles que percebem problemas vocais não necessariamente procuram cuidados profissionais.

ABSTRACT

PURPOSE: To investigate the learning factor during a perceptual-auditory analysis of an unusual task in three different groups. METHODS: 269 listeners, divided into three groups: 73 voice specialists Speech Language Pathologists (EG), 84 voice specialists Speech Language Pathologists (NEG); and 112 non-speech pathologists in the Naive Group (NG). They all completed a listening session that included 18 synthesized and 18 human voices with different types and degrees of deviation (50% of repetition for intra-rater consistency analysis). The task was to classify the voices as human or synthesized. We analyzed the learning factor by comparing the initial error percentage, first 18 voices, with the final, last 18 voices. RESULTS: EG presented less error towards the end of the task (25.5%) than at the beginning (28.6%) with statistical difference (p = 0.024). The error percentage of the beginning and the end of the task did not differ for the NEG and the NG (NEG beginning = 36.5%, end = 35.3%; NG beginning = 38.3%, end = 37.7%). CONCLUSION: The EG was the only group to present evidence of learning factor. Therefore, it seems that professional experience positively influences the perceptual-auditory analysis, which reinforces the impact of its training to become a voice specialist. Moreover, the voice specialists seem to be more prepared and more susceptible to use learning strategies to improve their performance during a perceptual-auditory analysis task, even if unusual.


OBJETIVO: Investigar o fator de aprendizagem durante uma tarefa perceptivo-auditiva para três grupos diferentes em uma tarefa não usual. MÉTODO: 269 ouvintes, divididos em três grupos: 73 no grupo dos fonoaudiólogos especialistas em voz (GE), 84 no grupo dos fonoaudiólogos não especialistas em voz (GNE) e 112 no grupo leigo (GL), dos não fonoaudiólogos. Todos foram submetidos a uma sessão de escuta que incluiu 18 vozes humanas e 18 vozes sintetizadas com diferentes tipos e graus de desvio, mais 50% de repetição para avaliar a consistência intraindivíduo. A tarefa era classificar as vozes como humana ou sintetizada. Analisou-se o fator de aprendizagem pela comparação da porcentagem de erros do começo, primeiras 18 vozes, e do final, últimas 18 vozes, da sessão de escuta. RESULTADOS: O GE foi submetido ao fator de aprendizagem, apresentando menos erros no final da tarefa (25,5%), do que no começo (28,6%), com diferença estatística (p = 0,024). O GNE e o GL não apresentaram diferença da porcentagem de erros no começo e no final da tarefa (GNE começo = 36,5%; GNE final = 35,3%; GL começo = 38,3%; GL final = 37,7%). CONCLUSÃO: O GE foi o único grupo que apresentou indícios evidentes do fator de aprendizagem. Parece que a experiência profissional influencia de modo positivo a análise perceptivo-auditiva, reforçando o impacto de um treinamento para se tornar um especialista em voz. Ainda, o especialista em voz parece estar mais preparado e mais suscetível a utilizar estratégias de aprendizagem para melhorar sua performance durante uma tarefa perceptivo-auditiva mesmo que pouco usual.

ABSTRACT

PURPOSE: To compare and to correlate the performance of women with behavioral dysphonia and without voice disorders in auditory processing tests and in the Voice Tone Reproduction Test (VTRT). METHODS: Forty women aged from 18 to 44 years participated and were divided in two groups: dysphonic (DG) and non-dysphonic (NDG). The participants underwent interview, hearing, otorhinolaryngology and voice assessments (voice record, VTRT through phonetography), and auditory processing assessment-using the Pitch Pattern Sequence (PPS) test and the Duration Pattern Sequence (DPS) test. The statistical analysis compared both groups, and there was a correlation test (P < 0.05). RESULTS: The NDG had a better performance in the PPS test (P = 0.000), in the VTRT test in the first attempt (P = 0.025), and in the total of correct answers (P = 0.017). There was a positive correlation between the PPS and both the first attempt of the VTRT and the total number of attempts. Regarding the DPS, there was a positive correlation for the left ear with the total number of VTRT attempts. CONCLUSIONS: Dysphonic women presented disorders in temporal auditory processing skills, revealing an important relation between vocal production and impairment of some central auditory functions. There was a positive correlation between the performance in the auditory processing assessment and the performance in voice tone reproduction in both groups. The VTRT may assist speech therapists and voice trainers in verifying difficulties of auditory perception of dysphonic women when the cause is due to behavioral tdysphonia.

ABSTRACT

PURPOSE: To develop a simple and quick-to-apply procedure for pitch-matching scanning that contains vocal imitation tasks of musical sounds of different tones and the temporal ordination of three different tones; to verify its applicability, by comparing the performance of musicians and non-musicians. METHODS: Participants were 32 adults of both genders without vocal, hearing and/or auditory processing complaints. They were equally divided into two groups: musicians group--MG and non-musicians group--NMG. All participants underwent the Pitch-matching Scanning that included musical stimuli compatible with men and women singing vocal range gathered into two types of tasks: isolate tones and three-tone sequences. Participants were instructed to listen to them and to reproduce them vocally. Voice samples were recorded, analyzed acoustically, and right and wrong matches for the two tasks were characterized. The variables regarding the comparison between groups and types of tasks were statistically analyzed. RESULTS: A difference was found between groups, and the MG presented greater number of right matches in both tasks. CONCLUSION: The Pitch-matching Scanning was developed and was sensitive to evaluate and compare the performance between groups. Thus, it can be used as a tool for pitch-matching tracking. Musicians presented better performance than non-musicians in the Pitch-matching Scanning.

ABSTRACT

OBJETIVOS: Elaborar um procedimento simples e de rápida aplicação contendo tarefas de imitação vocal de sons musicais de diferentes tons e de ordenação temporal de três tons; verificar sua aplicabilidade, comparando o desempenho de musicistas e não musicistas. MÉTODOS: Participaram 32 indivíduos adultos, de ambos os gêneros, sem queixas vocais, auditivas e/ou de processamento auditivo, que foram divididos igualmente em dois grupos: grupo musicistas - GM e grupo não musicistas - GNM. Todos passaram pela Triagem da Afinação Vocal, que incluiu estímulos musicais compatíveis com a tessitura vocal de homens e mulheres, agrupados em dois tipos de tarefas: tons isolados e sequências de três tons. Os participantes foram instruídos a ouvir os tons apresentados e reproduzí-los vocalmente. As emissões vocais foram gravadas, analisadas acusticamente e os acertos e erros cometidos nos dois tipos de tarefas foram caracterizados. As variáveis referentes à comparação entre os grupos e os tipos de tarefas foram analisadas estatisticamente. RESULTADOS: Houve diferença na comparação entre os dois tipos de tarefas para o GNM, o que não ocorreu com o GM. Foram observadas diferenças na comparação entre os grupos, sendo que o GM apresentou um maior número de acertos nos dois tipos de tarefas. CONCLUSÃO: A Triagem da Afinação Vocal foi criada e mostrou-se sensível para avaliação e comparação do desempenho entre grupos, podendo ser utilizada como instrumento de rastreamento de afinação vocal. Musicistas apresentaram melhor desempenho que não musicistas na Triagem da Afinação Vocal.
