Abstract

Purpose To detect and discuss the value of using transiently evoked otoacoustic emissions (TEOAE) and distortion-product otoacoustic emissions (DPOAE) in the diagnosis and monitoring noise-induced hearing loss. Methods 115 noisy factory workers (201 ears) with better than 40 dB HL hearing threshold and 47 normal people (94 ears) were detected by TEOAE and DPOAE. Results The difference of presence of TEOAE and DPOAE between the two groups was statistically significant. Conclusion Both TEOAE and DPOAE can give useful indication of noise-induced hearing loss.
