Abstract Introduction Tinnitus is a conscious perception of a sound resulting from abnormal activity within the nervous system. A relevant percentage of tinnitus patients report symptoms severe enough to significantly affect quality of life, including sleep disorders. Objectives To analyze the sleep quality, insomnia, daytime sleepiness, and risk of obstructive sleep apnea (OSA) in participants with tinnitus. Methods The sample comprised 18 adults and older adults aged between 18 and 85 years old (mean age = 58.7 ± 17.5 years old), females and males, with complaint of continuous tinnitus for > 1 month. The instruments used were the Tinnitus Handicap Inventory (THI) questionnaire, the Insomnia Severity Index, the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, and the STOP-Bang questionnaire. Results By means of the THI questionnaire, the tinnitus severity degree reported by most participants was mild (27.8%) and moderate (27.8%), having a positive (r = 0.582) and significant (0.011) correlation to sleep quality, measured by means of the Pittsburgh questionnaire. There was a positive correlation between the Insomnia Severity Index and tinnitus handicap (r = 0.499; p = 0.035). A total of 72.2% of the participants self-assessed their sleep quality as poor, in addition to moderate insomnia (27.8%), although there is low risk of OSA (66.7%), without complaints of excessive daytime sleepiness (72.2%). Conclusion Subjects with tinnitus complaint self-rated their sleep quality as poor. Moreover, the higher the reported tinnitus handicap, the greater the symptoms of insomnia. There was no influence of tinnitus in relation to daytime sleepiness and no relationship between the severity of tinnitus and the risk of OSA.

ABSTRACT Purpose The aim of the present study is to translate, adapt, and cross-culturally validate the Brazilian Portuguese version of the questionnaire Hearing Protection Assessment Questionnaire (HPA). Methods The original instrument, developed in English, seeks to assess barriers and supports related to the use of hearing protection devices (HPD), as well as workers' knowledge, habits and attitudes towards occupational noise. The translation, adaptation, and cross-cultural validation of the questionnaire consisted of five steps: Translation of the questionnaire from English to Portuguese; 2) Reverse translation from Portuguese to English; 3) Analysis of the instrument by three experts in the field; 4) Pre-test of the questionnaire with ten workers; 5) Application of the instrument to 509 workers in a meatpacking industry after the pre-employment medical exam. Results The results indicate the construction and content validity of the Brazilian Portuguese version for use with a working population and its internal consistency. Conclusion This study resulted in the translation, cultural adaptation, and validation of the Hearing Protection Assessment Questionnaire (HPA), in order to be used to assess the use of individual hearing protection in the occupational field, called Hearing Protection Assessment Questionnaire (HPA).

ABSTRACT Purpose To analyze the possible differences among the hearing of farmers and their families when compared to the population not exposed to pesticides. Methods Cross-sectional study with 70 smallholder family farmers (research group), with the mean age of 39.7 years, of both sexes and a mean of 23.7 years of exposure to pesticides. We included a control group with 71 participants of both sexes with the mean age of 39.5 years, not exposed to either noise or chemical substances, to compare the results. In stage 1, both groups were submitted to conventional and high-frequency audiometry, and acoustic immittance. In stage 2, only people with normal hearing were submitted to the evoked otoacoustic emissions and suppression effect on transient otoacoustic emissions. Results Significant differences were observed between the groups in the conventional pure-tone and in the high-frequency audiometry, as well as in the acoustic reflex. The most affected frequencies in the conventional pure-tone audiometry ranged from 3 to 6 kHz and, in the high-frequency audiometry, from 9000 to 11200 Hz. As for the transient otoacoustic emissions, the worse suppression effect results were found in the research group. Conclusion There were differences among the hearing of family farmers and the control group. The conventional auditory thresholds are related to the group, age and sex. Farming is associated with impairments in the basal region of the cochlea, absence of acoustic reflex, reduced signal-to-noise ratio of the transient otoacoustic emissions, and dysfunction in the olivocochlear efferents of the auditory system.

RESUMO Objetivo Analisar as possíveis diferenças na audição de agricultores e suas famílias em comparação com população não exposta aos agrotóxicos. Método Estudo transversal, com 70 participantes (grupo pesquisa), com média de idade de 39,7 anos, de ambos os sexos, proprietários de pequenos estabelecimentos agrícolas vinculados a agricultura familiar e tempo de exposição médio aos agrotóxicos de 23,7 anos. Um grupo controle com 71 participantes de ambos os sexos, sem exposição a ruído e agentes químicos, com idade média de 39,5 anos, foi incluído para a comparação dos resultados. Na etapa 1, ambos os grupos foram submetidos a audiometria convencional e de altas frequências e imitanciometria. Na etapa 2, somente os normoouvintes foram submetidos as emissões otoacústicas evocadas e efeito de supressão das emissões otoacústicas transientes. Resultados Observou-se diferenças significativas entre os grupos para audiometria tonal convencional e de altas frequências, e no reflexo acústico. As frequências mais afetadas na audiometria tonal convencional foram 3 a 6kHz e na audiometria de altas frequências foram as frequências de 9.000 e 11.200 Hz. Nas emissões otoacusticas transientes, observou-se no efeito de supressão piores resultados no grupo de pesquisa. Conclusão Conclui-se que houve diferenças na audição dos agricultores familiares em comparação com o grupo controle. Os limiares auditivos convencionais estão relacionados em função do grupo, idade e gênero. O trabalho na agricultura está associado com o comprometimento na região basal da cóclea, à ausência de reflexo acústico, à redução da relação sinal/ruído das emissões otoacústicas transientes e à disfunção do sistema auditivo eferente olivococlear.

OBJECTIVES: Assessing infants’ hearing is of utmost importance, as hearing at this phase is required for the development of oral language. Through hearing, human beings are capable of developing communication. The Brainstem Auditory Evoked Potentials are an indispensable test to diagnose deafness in infants. This study aimed to analyze the results of the Brainstem Auditory Evoked Potentials in children with risk factors for hearing loss. METHODS: This cross-sectional study analyzed the Brainstem Auditory Evoked Potentials in 123 infants aged 1 to 24 months at a hearing health care service. The Vivosonic Integrity V500 equipment, which enabled the child to be awake while the testing was carried out, was used in this study. The data were compared by gestational age and sex, according to the standards suggested in the equipment handbook. RESULTS: A significant difference was verified for age ranges 4 to 6 months, 13 to 15 months (waves I and V), and 7 to 9 months (wave V). The lower values in absolute wave latencies were comparable to data from the equipment handbook, justifying the need for standardization of the screening process. CONCLUSION: There are some differences between the standards in the equipment handbook and those observed in our study. These results will serve as a reference for the standardization of the equipment used in the hearing health care service.

RESUMO O objetivo desse relato de casos clínicos é apresentar quatro casos de fumicultores com perda auditiva devida à exposição laboral a agrotóxicos. Trata-se de um estudo de caso qualitativo, incluindo 3 casos de perda auditiva sensório-neural com nexo causal (Casos 1, 2 e 4) e um caso (Caso 3) de perda auditiva sensório-neural compatível com ototoxidade por agrotóxicos, com nexo baseado, sobretudo, nos transtornos neuropsiquiátricos menores. A casuística foi constituída por trabalhadores rurais com problemas de saúde, em idade produtiva, com início de atividade laboral precoce, expostos a múltiplos agrotóxicos, incluindo os organofosforados. Os sintomas auditivos e neurovegetativos relatados foram: desconforto a sons (n=2), dificuldade de compreender a fala (n=3), tontura (n=2) e desequilíbrio (n=2). A audiometria tonal revelou perda auditiva sensório-neural em uma ou mais frequências altas e um dos casos apresentou alteração no Potencial Evocado Auditivo de Tronco Encefálico. Foi evidenciada associação entre perda auditiva e o trabalho nos fumicultores expostos a agrotóxicos, com danos auditivos periféricos nos quatro casos e dano central em um dos casos, demonstrando a necessidade da avaliação audiológica completa para populações expostas a agrotóxicos.

ABSTRACT The Purpose of this case report is to present four cases of tobacco growers with hearing loss due to occupational exposure to pesticides. A qualitative case study comprising three cases of sensorineural hearing loss with causal nexus (Cases 1, 2 and 4), and one (Case 3) of sensorineural hearing loss compatible with ototoxicity by pesticides, with causal nexus mainly based on minor neuropsychiatric disorders. The sample was composed of rural workers with health problems, in working age, having started working early in life, exposed to various pesticides, including organophosphates. The auditory and neurovegetative symptoms reported were noise discomfort (n = 2), speech perception difficulty (n = 3), dizziness (n = 2), and imbalance (n = 2). The pure-tone audiometry revealed a sensorineural hearing loss in one or more high frequencies, and one of the cases presented alteration in the brainstem auditory evoked potentials. There is evidence, in this study, of an association between hearing loss and work in tobacco growers exposed to pesticides, with peripheral auditory damage in four cases, and central damage in one of them. Thus, the need for a complete audiological evaluation of pesticide-exposed populations is highlighted.

RESUMO Objetivo: caracterizar os fonoaudiólogos e as ações que desenvolvem na área da saúde do trabalhador com relação ao Programa de Preservação Auditiva (PPA). Métodos: estudo quantitativo, transversal, com 74 fonoaudiólogos de diversas regiões do Brasil que trabalham em Saúde do Trabalhador e Audiologia. Os participantes responderam a um questionário sobre seu perfil profissional, formação e atuação em relação aos componentes do PPA. Para a análise dos dados utilizou-se procedimentos estatísticos (teste Qui-Quadrado e o teste de diferença de proporções, ao nível de significância 0,05 - 5%) em relação às variáveis sexo, idade, função, tempo de formado e formação acadêmica em saúde e segurança do trabalho. Resultados: os fonoaudiólogos, a maioria mulheres, que relataram realizar o PPA, tinham idade superior a 30 anos; fizeram cursos de pós-graduação específica, mas ainda apresentavam dúvidas em relação à implantação do Programa; estavam em empresas com mais de 1000 funcionários, independentemente de seu regime de trabalho, realizando ações como: gerenciamento auditivo e orientação sobre utilização correta de protetores auriculares. Conclusão: há ainda um número elevado de fonoaudiólogos na área de Saúde do Trabalhador que não desenvolvem um programa de preservação auditiva na íntegra.

ABSTRACT Objective: to characterize speech-language pathologists/audiologists and their interventions in the occupational health area, regarding the Hearing Prevention Program (HPP). Methods: a cross-sectional, quantitative study with 74 speech-language pathologists/audiologists from several regions of Brazil, working in the areas of Occupational Health and Audiology. The participants answered a questionnaire on their professional and educational profile, as well as on their work related to the HCP components. For data analysis, statistical procedures were used (Chi-Square Test and the test of difference in proportions, at the significance level of 0.05 - 5%), in relation to the variables of gender, age, job position, time since their graduation and academic training in occupational safety and health. Results: the speech-language pathologists/audiologists, mostly women, who reported performing the HPP, were older than 30 years, had specific postgraduate courses, but still had doubts about the Program implementation, they worked for companies with over 1,000 employees, disregarding their employment status, performing interventions, such as: hearing management and guidance on the correct use of ear protectors. Conclusion: a high number of speech-language pathologists in the Occupational Health area have not developed a complete hearing conservation program to this date.

Abstract Introduction Hearing is the main sensory access in the first years of life. Therefore, early detection and intervention of hearing impairment must begin before the first year of age. Objective To analyze the results of the electrophysiological hearing assessment of children at risk for hearing loss as part of the newborn hearing screening (NHS). Methods This is a cross-sectional study held at a hearing health public service clinic located in Brazil, with 104 babies at risks factors for hearing loss referred by public hospitals. A questionnaire was applied to parents, and the auditory brainstem response (ABR) test was held, identifying those with alterations in the results. The outcome of the NHS was also analyzed regarding risk factor, gestational age and gender. Results Among the 104 subjects,most of them weremale (53.85%), and the main risk factor found was the admission to the neonatal intensive care unit (NICU) for a period longer than 5 days (50.93%). Eighty-five (81.73%) subjects were screened by NHS at the maternity and 40% of them failed the test. Through the ABR test, 6 (5.77%) infants evidenced sensorineural hearing loss, 4 of them being diagnosed at 4months, and 2 at 6 months of age; all of them failed the NHS and had family history and admission atNICU for over 5 days as themost prevalent hearing risks; in addition, familymembers ofall children perceived their hearing impairment. Conclusion Advances could be observed regarding the age of the diagnosis after the implementation of the NHS held at the analyzed public service clinic.

RESUMO Objetivo: caracterizar o perfil audiológico de mototaxistas e analisar o risco de suas exposições ao ruído. Métodos: estudo transversal, com 17 mototaxistas de uma cidade no litoral do Sul do Brasil, 2008. Realizou-se a avaliação do ruído no posto de trabalho e durante um trajeto padrão. Calculou-se a dose de exposição ao ruído, aplicou-se um questionário sobre a percepção de efeitos auditivos e extra-auditivos e realizou-se avaliação auditiva por audiometria tonal limiar. Resultados: no posto de trabalho o ruído esteve em torno de 73 dBA (decibéis, escala A) e no trajeto, apresentou dose de ruído superior a 100% para uma jornada de trabalho de 12 horas. A irritabilidade e a fadiga/estresse após o trabalho foi relatada por 58,8% dos sujeitos e 52,9% deles apresentaram perdas auditivas destes, cinco com características de PAIR. Porém, os mototaxistas não relacionaram as consequências à saúde com a exposição contínua ao ruído. Conclusão: os mototaxistas apresentaram risco auditivo e 29% do total pesquisado, alterações auditivas com características sugestivas de perda induzida pelo ruído, o que torna a implantação de Programas de Conservação auditiva de grande valia para esta classe de trabalhadores.

ABSTRACT Objective: to characterize the hearing profile of motorcycle taxi drivers and analyze the risk of their exposure to noise. Methods: a cross-sectional study with 17 motorcycle taxi drivers of a city on the Southern coast of Brazil, in 2008. Noise was measured at workplace and during a standard route. The dose of exposure to noise was calculated, a questionnaire on the perception of auditory and extra-auditory effects was applied and an auditory hearing assessment through threshold tonal audiometry was performed. Results: at workplace, noise was around 73dBA (decibels, A scale), and while commuting, noise was above 100% for a 12-hour working day. Strain and stress/fatigue after work were reported by 58.8% of the subjects and 52.9% of them showed hearing losses, five presenting characteristic noise-induced hearing losses (NIHL). However, the motorcycle taxi drivers did not associate the adverse health effects to the continuous exposure to noise. Conclusion: the motorcycle taxi drivers presented hearing risk, 29% of them presenting hearing alterations with characteristics suggestive of noise-induced hearing loss, which makes the implementation of auditory conservation programs of extremely importance for this class of workers.

RESUMO Objetivo Avaliar a efetividade das ações educativas em saúde auditiva desenvolvidas em uma lavanderia hospitalar. Método Pesquisa avaliativa de abordagem quantitativa realizada numa lavanderia hospitalar.

Houve melhora na média de pontuação com 35 (97,22%) questões apresentando pontuação maior que 4 (considerada resposta adequada). O gênero feminino apresentou conhecimentos inferiores ao masculino, porém, após as oficinas, essas diferenças não foram observadas no GI. A escolaridade não foi um fator relevante neste estudo. Conclusão A proposta educativa pautada na metodologia problematizadora ampliou o conhecimento referente à saúde auditiva no trabalho entre os participantes.

ABSTRACT Objective Evaluate the effectiveness of educational interventions on hearing health developed at a hospital laundry. Methods Quantitative assessment conducted at a hospital laundry. The study sample comprised 80 workers of both genders divided into two groups: Study Group (SG) and Control Group (CG). The educational interventions in hearing preservation were evaluated based on a theoretical approach using the Participatory Problem-based Methodology in five workshops. To assess the results of the workshops, an instrument containing 36 questions on knowledge, attitudes, and practices in hearing preservation at work was used. Questionnaires A and B were applied prior to and one month after intervention, respectively. The answers to both questionnaires were analyzed by group according to gender and schooling. Results Results of the pre-intervention phase showed low scores regarding knowledge about hearing health in the work setting for both groups, but significant improvement in knowledge was observed after intervention in the SG, with 77.7% of the answers presenting significant difference between the groups. There was also an improvement in the mean scores, with 35 responses (95.22%) presenting scores >4 (considered adequate). The women presented lower knowledge scores than the men; however, these differences were not observed in the SG after the workshops. Schooling was not a relevant factor in the assessment. Conclusion The educational proposal grounded in the Participatory Problem-based Methodology expanded knowledge about hearing health at work among the participants.

Resumo Objetivo: analisar a produção científica sobre intervenções educativas desenvolvidas para a prevenção auditiva de trabalhadores expostos ao ruído. Método: revisão integrativa, descritiva e analítica de produções científicas publicadas no período 2005-2016, em idioma inglês e português, disponíveis nas bases de dados LILACS, MEDLINE, PubMed, SciELO e Google Scholar. Resultados: inicialmente foram identificados 137 artigos e após aplicação dos critérios de inclusão e exclusão, 16 artigos foram selecionados (9 internacionais, 7 nacionais) para análise. As categorias profissionais nos estudos foram: mineiros, operários da construção civil, bombeiros, operários de empresa de equipamentos eletrônicos, agricultores, trabalhadores de frigorífico, teleoperadores, trabalhadores de universidade, pescadores industriais e trabalhadores de empresa alimentícia. A maioria dos estudos visava a mudança de atitude em relação aos protetores auriculares. Os estudos internacionais basearam-se em teoria comportamental e pretendiam aumentar a intenção de uso e a utilização de protetores auriculares; apenas um deles visou a redução do nível de ruído no ambiente de trabalho. Dos estudos nacionais, 3 utilizaram abordagens comportamentais e 4 desenvolveram ações educativas, mas somente 1 referiu metodologia participativa. Conclusão: intervenções educativas focadas apenas na utilização de protetores auriculares mostraram-se insuficientes, indicando a necessidade de ações educativas mais abrangentes e participativas, associadas a medidas de controle ambiental.

Abstract Objective: to analyze the scientific production about educational interventions aimed at prevention of Noise-Induced Hearing Loss at work. Method: descriptive and analytical integrative review of scientific literature published between 2005-2016, in English and Portuguese, available in LILACS, MEDLINE, SciELO, PubMed and Google Scholar. Results: initially, 137 articles were identified; after application of inclusion and exclusion criteria, 16 articles (9 international, 7 national) were selected for analysis. The occupational categories included in the studies were: miners, firefighters, telemarketers, farmers, industrial fishermen, and workers of universities, electronic equipment industry, construction, meat processing, and food companies. Most studies aimed at changing the attitude towards hearing protectors. The international investigations were based on behavioral approaches and had the purpose of increasing intent of use and use of hearing protectors; only one of them was aimed at reducing noise level in the work environment. Among the national studies, three adopted behavioral approaches, and four developed educational activities, but only one mentioned a participatory methodology. Conclusion: educational interventions, which were only focused on the use of hearing protectors, were insufficient, indicating that they must be more comprehensive and participatory, as well as associated with environmental control measures.

RESUMO Objetivo: analisar a percepção e conhecimento de odontólogos sobre o ruído, sua prevenção e efeitos na saúde e qualidade de vida. Métodos: estudo transversal, realizado com 54 dentistas de ambos os gêneros. Aplicou-se dois questionários: um abordando a percepção e conhecimento sobre exposição a ruído e seus efeitos e outro sobre Qualidade de Vida (SF-36). Resultados: no ambiente de trabalho odontológico, o ruído foi percebido em média intensidade e considerado um risco à saúde. Alguns profissionais (59,2%) relataram conhecer métodos de prevenção dos efeitos do ruído, porém não os utilizam. As principais queixas e sintomas foram irritabilidade, dificuldade na compreensão da fala e zumbido. A percepção sobre a Qualidade de Vida foi pior entre os homens. Houve associação entre o domínio Dor com a percepção da intensidade do ruído. Conclusão: o ruído foi considerado, independente do gênero, como nocivo à saúde e se relacionou com a percepção de dor musculoesquelética. Foram relatados sintomas e queixas associados ao ruído que podem impactar negativamente a atividade profissional dos odontólogos, mas a maioria não adota medidas preventivas.

ABSTRACT Purpose: to analyze the perception and knowledge of dentists on occupational noise, its prevention, and effects on their health and quality of life. Methods: a cross-sectional study carried out with 54 dentists of both genders. Two questionnaires were applied: one addressing issues of perception and knowledge on noise and its effects, and another on Quality of Life (SF 36). Results: the workplace noise was considered within medium intensity, and a health risk. Some professionals (59.2%) reported knowing noise prevention methods, although they do not use them. Complaints and the most frequently reported symptoms were irritability, difficulty in understanding speech and tinnitus. The perception of the Quality of Life was worse among men. There was association between pain and perception of noise intensity. Conclusion: noise was considered, regardless of gender, harmful to health and associated with perception of musculoskeletal pain. Symptoms and complaints caused by noise have been reported to negatively impact the professional activity of dentists, however, most of them do not adopt preventive measures.

Abstract Introduction Nowadays noise remains the third largest cause of environmental pollution on Earth. It appears that despite the existing noise control legislation the issue deserves further supervision by the public authorities so that the ceilings established for the various activities are observed. People exposed to noise are more likely to develop numerous auditory and non-auditory problems directly impacting persona family and working life. Objectives The objective of this study is to research and consequently understand how the population of students of a youth and adult school in Curitiba perceives noise pollution as well as look into the actions that the school adopts in order to guide the students on the topic. Method We applied a structured questionnaire to 120 individuals and assessed the following variables: characterization of the place of residence occupation leisure health and perception of soundscapes. We also applied a closed questionnaire about educational actions for noise pollution to the school’s geography teacher. Results Questionnaire responses show that people perceive noise in the most diverse environments they frequent and are able to identify the source of the noise but this perception proved fragile as themajority does not takemeasures to prevent ormitigate these noises. At school there are no actions aimed at environmental education on the subject studied. Conclusion The studied group does not perceive the noise as a harmful agent and does not prevent themselves from it and the school not work contents related to noise pollution leaving a significant gap in the awareness process of this population.

RESUMO Objetivo Analisar a percepção e o conhecimento dos profissionais de saúde que atuam na rede de Atenção Primária à Saúde do Município de Curitiba - Paraná sobre a notificação compulsória da Perda Auditiva Induzida pelo Ruído (PAIR) no, Sistema de Informação de Agravos de Notificação (SINAN). Método Utilizando como método o estudo transversal na cidade de Curitiba, analisando a percepção e o conhecimento dos profissionais de saúde que atuam na rede de Atenção Primária à Saúde do Município de Curitiba sobre a notificação compulsória da PAIR no SINAN. Aplicou-se ainda um questionário semiaberto em profissionais de saúde da atenção básica sobre conhecimento sobre a PAIR e sua notificação. Resultados Dos profissionais da atenção básica, 50% eram médicos com faixa etária de 26 a 30 anos. Dentre os profissionais, 56,2% relataram estarem preparados para identificar problemas de saúde relacionados ao trabalho, porém apenas 43,7% sentem-se aptos a identificar casos de PAIR. Entre as facilidades na notificação, relataram descentralização da assistência à saúde próxima à residência do usuário, encaminhamento para referência em medicina do trabalho e prontuário eletrônico na UBS; como dificuldades, relataram a não formação específica em saúde do trabalhador e falta de capacitação, tempo reduzido para consultas e receio. Conclusão os profissionais de saúde conhecem as características e sentem-se aptos para identificar os casos de PAIR, mas ainda não notificam os casos suspeitos de PAIR e não percebem a Saúde do Trabalhador como um programa institucionalizado fazendo parte do serviço.

ABSTRACT Objective The article aims to analyze the perception and knowledge of health professionals working in primary health care networks in the Municipality of Curitiba – Paraná, regarding the compulsory notification of Induced Hearing Loss Noise (NIHL) in the National Notifiable Diseases Information System (SINAN). Methods We performed a transversal cohort study in Curitiba, analyzing perception and knowledge of health professionals working in the primary health care networks in the Municipality of Curitiba, regarding the compulsory notification of NIHL in SINAN, from 2007 to 2014, featuring the reported cases and exploring the situational analysis of the NIHL notification, through a questionnaire and a structured news conference. Results The primary care professionals’ survey showed that 50% were doctors and the predominant age group was 26-30 years, with 56.2% reported as being able to identify health problems related to work, but only 43.7% feel able to identify cases of NIHL. Conclusion It was found that health professionals know the features and feel able to identify cases of NIHL, but still do not report suspected NIHL cases and do not consider occupational health an institutionalized program that is part of the service.

Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those thatmay exist in the workplace and lead to workers hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.
