ABSTRACT
Introduction The presence of noise in our society has attracted the attention of health professionals, including speech-language pathologists, who have been charged along with educators with developing hearing conservation programs in schools. Objective To describe the results of three strategies for awareness and hearing preservation in first to fourth grades in public elementary schools. Methods The level of environmental noise in classrooms was assessed, and 638 elementary school students from first to fourth grades, 5 to 10 years of age, were audiologically evaluated. After the evaluations, educational activities were presented to children and educators. Results The noise level in the classroom ranged from 71.8 to 94.8 A-weighted decibels. The environment of the classroom was found to promote sound reverberation, which hinders communication. Thirty-two students (5.1%) presented hearing alterations. Conclusion The application of strategies for a hearing conservation program at the school showed that noise is present in the room, and hearing loss, sometimes silent, affects schoolchildren. Students and teachers were aware that hearing problems can be prevented. Avoiding exposure to noise and improving the acoustics in classrooms are essential. .

Objetivo analisar a eficiência de oficinas em saúde auditiva como proposta de ações educativas para trabalhadores expostos ao ruído. Métodos estudo de intervenção, em 15 trabalhadores do sexo masculino, expostos ao ruído em uma empresa alimentícia. Etapas (1) avaliação auditiva dos trabalhadores, (2) aplicação do questionário “Crenças e atitudes sobre proteção auditiva” (NIOSH,1996) versão A na amostra, (3) elaboração e realização de 3 oficinas, contemplando alguns aspectos da metodologia participativa, com os temas: anatomofisiologia da audição, efeitos do ruído, prevenção, diagnóstico e consequências da Perda Auditiva Induzida por Ruído (PAIR), ruído e seu controle, utilização de protetores auriculares, (4) aplicação do questionário versão B para avaliação das oficinas. Comparou-se a apreensão de conhecimentos pelos trabalhadores por meio das diferenças de pontuação encontradas no questionário versão A e B. Resultados entre os trabalhadores investigados, com tempo médio de trabalho de 31,5 anos, 40% apresentaram PAIR bilateralmente. Após a aplicação das oficinas houve uma melhora significante em três áreas temáticas avaliadas: Percepção da suscetibilidade de adquirir uma perda auditiva, Percepção dos benefícios de uma ação preventiva e Mudanças nas intenções de comportamento. Conclusão a concepção pedagógica do tipo Participativa adotada, contribuiu para a reflexão dos trabalhadores sobre a preservação de sua audição e saúde frente ao ruído.

Purpose the effectiveness’ analysis of workshops on hearing health as proposed educational actions in health workers exposed to noise. Methods intervention study of 15 male worker exposed to noise in a food industry. Stages (1) assessment of hearing profile, (2) application of the questionnaire” Beliefs and attitudes about hearing protection” (NIOSH, 1996) – version A; (3) formulate and conduct three workshops covering some aspects of participatory methodology, with the following themes: anatomy-physiology of hearing, effects of noise, prevention, diagnosis of had noise induced hearing loss, consequences of PAIR, noise and its control, use of ear protections. (4) questionnaire application - version B for workshops evaluation. They were compared with seizure or retention of knowledge through the differences in scores found in questionnaires version A and version B. Results among investigated workers (15), the average working average working time was 31,5 years, all males showed that 40% had noise induced hearing loss bilaterally. After application of the workshops there was a statistically significant improvement in tree thematic areas, namely: a) Perception of susceptibility to developing a hearing loss, b) Perceived benefits of preventive action and c) Changes in behavioral intentions. Conclusion the pedagogical design of the Participatory type contributed to the reflection of the workers about preserving your hearing and health in the noise. Using the questionnaire of beliefs and attitudes led to the identification of issues that need to be addressed in other educational activities. .
