“…Os mesmos testes aplicados com ruído causaram uma diminuição dos índices com piora de cerca de 20% 12 . As alterações auditivas sugestivas de PAIR em metalúrgicos jovens avaliados por outros autores, totalizaram 21% e 41% dos avaliados, respectivamente 13,14 . Além da perda auditiva, as pessoas expostas a ruído ocupacional costumam relatar diversas queixas.…”

“…A quantidade de alterações observadas no presente estudo é maior que o observado por outros pesquisadores que encontraram percentuais de perda auditiva variando de 21% a 41% em trabalhadores expostos a ruído ocupacional 11,13,14,20,48 . Conhecidamente, a exposição a ruídos de intensidade elevada pode resultar em uma perda auditiva temporária ou permanente 4 .…”

“…Such devices show the sound pressure level (SPL) corresponding to the selected frequency band (sound spectrum). Thus, environment noise monitoring helps in the acoustic classification of operational units, enabling the identification of the noisiest places and equipment, collecting information which will be used to select and optimize individual hearing protection devices 2,3 . Audiometric evaluation is the most used procedure in environments with noise above 85 dB(A).…”

“…Upon comparing the results obtained in conventional audiometry with those from high frequency audiometry in workers exposed and in those not exposed to noise, a study showed that the tonal thresholds were significantly higher in the high frequencies (p < 0.05) in the group with noise exposure, concluding that such approach enabled the early detection of hearing loss among the workers 6 . Despite numerous recent studies assessing the effects of noise in worker's health 2, , studies utilizing the combination of environmental with biological monitoring are still rare. We should explore more the analysis of the frequency spectrum in the work environment.…”

“…In the organ of Corti the main changes occur which are responsible for hearing loss induced by noise because their outer hair cells are extremely sensitive to high and prolonged sound pressure, with subsequent enzymatic and energy reduction, as well as decreased oxygen and nutrients. With cell death the space is filled by scar formation, causing the permanent loss of hearing ability 11,12 . Given the proven organic noise changes on the individual's body, the realization of this study aimed to measure the sound pressure level emitted by the MRI machine for examination of the skull and verify the auditory sensations described by patients after completion of the examination, since it is not common the hearing protection in Diagnostic Imaging centers.…”
