“…Being so, the reduction of amplitude can predict possible auditory alterations. In the present study, it was observed that the individuals who use earphones present inferior otoacoustic emissions amplitude compared to those who don't use earphones, even though presenting normal hearing degree in the tonal audio metry 2,8,10,12,14,15,17,27 . It is important to highlight that even knowing that the constant use of portable music players can…”

“…Noise intensity, exposure time and physical characteristics will determine how much it can damage hearing health 5,6 . The intensity, the kind of noise, its duration and quality are determining in the hearing alteration acquisition process 2,[6][7][8] were clarified and the free and informed consent term was signed. Upon the signing of the free and informed consent term, each one of the participants answered the data collecting questionnaire developed to be used in research previously carried out on the same theme and adapted by researchers to be used in the present study ( Figure 1).…”

Objetivos analisar a relação entre o uso de fones de ouvidos e os comprometimentos auditivos e extra-auditivos provocados pelos tocadores portáteis de música. Métodos a proposta foi coletar dados, por meio de um questionário respondido pelos participantes. Realização dos exames audiométricos: audiometria tonal e vocal; imitânciometria e pesquisa dos reflexos acústicos; emissões otoacústicas transientes e emissões otoacústicas produto de distorção, posteriormente os dados foram comparados entre os indivíduos de um mesmo grupo e os grupos foram comparados entre si (grupo experimental e grupo controle). Para a análise estatística foi utilizado o teste Qui-Quadrado e exato de Fisher. Resultados algumas das variáveis investigadas, tais como o uso de fones de ouvido de 1 a 2 horas diárias, a presença de queixas auditivas e extra-auditivas, exposição a níveis de pressão sonora elevados extra-ocupacional uma vez por semana, ser não fumante, não usar medicamentos controlados e não apresentar zumbido possuíram frequência estatisticamente significante para o grupo experimental. Em relação às queixas auditivas houve diferença estatisticamente significante entre os grupos experimental e controle para sensação de ouvido abafado e sensação de rebaixamento auditivo. Conclusão os sintomas temporários indicam os potenciais efeitos nocivos de ouvir tocadores portáteis de música por uma hora ao dia. Pesquisas ainda são necessárias para avaliar os prejuízos de longo prazo ao sistema auditivo.

Conflict of interest: non-existentheadache, physiological changes in heart rate, blood pressure, sleep disorders, several digestive, vestibular, neurological and behavioral disorders such as irritability, tiredness, decreased productivity, noise intolerance, anguish, anxiety, depression, stress, among others 2,3 . In relation to the necessary time exposition for triggering noise-induced hearing loss, the highest number of impairing rates occurs between five and seven years, decreasing loss progression rate until fifteen years when it tends to stabilize as long as exposition conditions and absence of other causative factors are kept 2,4,5 . Noise-induced hearing loss characterized by irreversible cochlear damage, in configuration of high-frequency features one of the most serious, prevalent problems for workers' health. Studies have evidenced that there has not been a reduction in work-related deafness 6 . Occupational noise is also present in hospitals, mainly in hospital laundries where continuous exposition to high levels of sound pressure may bring about permanent changes in workers' hearing INTRODUCTIONAmong all agents that may result in occupational hazard, noise certainly appears as the most frequent one, exposing a larger number of individuals.1 It is known that workers exposed to high levels of noise, above the tolerance threshold, complain about hearing loss and tinnitus, besides NOISE EFFECTS ON HOSPITAL LAUNDRY WORKERS' HEARING Efeitos do ruído na audição de trabalhadores de lavanderia hospitalarFrancisca Pinheiro Fontoura ABSTRACT Purpose: to carry out a characterize the hearing profile of workers from a hospital laundry. Method: crosscut study, with 95 workers, males and females, age averaging 38.23, held at the laundry of a public hospital located in the city of Curitiba, Parana State/Brazil. Documental laundry analysis was carried out (Medical Control and Occupational Health Program and Environmental Risk Prevention Program), noise measurement, anamnesis-applied hearing evaluation, tonal threshold audiometry, acoustic immittance, and transient otoacoustic emission testing. Audiograms were analyzed through clinical and occupational criteria (Labor Ministry/ Regulatory Norm 7). Results: noise levels found were 77.0 to 99.0 dB(A), 37.89% audiograms were altered, among them, 18.94% suggesting noiseinduced hearing loss, mainly among the clothes folders. The test of otoacoustic emissions showed no transient responses in 13 subjects with no emissions in some ears. Conclusion: the laundry is a hazardous place for hearing loss, thus preventive measures, such as Hearing Conservation Programs must be adopted.

“…The occupational hearing loss has been mostly only attributed to noise although there are other agents that might contribute to its potentiation, among them pesticides [2][3][4][5][6][7][8][9][10] . Studies have linked exposure to otoagressives agents, noise and ototoxics, at higher frequencies above 8kHz, before the others [11][12][13] .…”
