||Comparison of otoacoustic emissions among workers exposed and not exposed to noise
||Comparaciˇn de emisiones otoac˙sticas en individuos expuestos y no expuestos al ruido ocupacional [in Spanish]|
||2nd Quarter 2004, Vol.11, No.40, p.7-11. Illus.
||In this study, the average amplitude of distortion product otoacoustic emissions (DPOAE) were compared in 36 volunteers aged between 20 and 30 years, occupationally exposed to noise for at least a year but wearing hearing protectors all day, and 36 unexposed controls of similar age. Results of audiometric tests were normal in both groups. The duration of exposure had little influence on the DPOAE amplitudes. This article underscores the importance of wearing hearing protectors during exposure to noise for avoiding hearing loss.
