Abstract
OBJECTIVE: To understand the value of using distortion product of otoacoustic emissions(DPOAE) in monitoring noise-induced hearing-loss. METHOD: The amplitude and the positive rates of DPOAE were detected in 102 well-drilling workers (195 ears). RESULT: The amplitude and the positive rates of DPOAE declined significantly in noise groups against control. With the increase of working-age the positive rates of DPOAE was decrease. The DPOAE amplitudes and the positive rates of noise group with normal pure tone threshold were obvious lower than that in controls. There were negative relationship between pure tone threshold in high-frequency and the positive rates. CONCLUSION: The DPOAE can reflect the cochlea's function of labors working in noise condition well. Contrast with the pure tone audiometry, DPOAE was more sensitive and more objective.
