BACKGROUND: articles related of otoacoustic emissions in differential diagnosis of noise-induced hearing loss (NIHL). PURPOSES: to demonstrate the importance of using otoacoustic emissions in the differential diagnosis of noise-induced hearing loss (NIHL). CONCLUSION: it was confirmed that both the transient-evoked otoacoustic emissions (TEOAE) and distortion-product otoacoustic emissions (DPOAE) are useful in the early diagnosis of and the TEOAE and are more sensitive to temporary alterations in the DPOAE threshold, and DPOAE stand out more effectively in the early diagnosis of NIHL in individuals with apparently normal hearing responses by capturing responses more acute frequencies in that are first affected in NIHL. It is also believed that this study can benefit the population on the NIHL prevention and control and foment the creation of public policies that shall contribute to the prevention of hearing impairment within the occupational field.
