title: Effect of short duration broad band noise on transient evoked otoacoustic emission amplitude.
abstract: Transient evoked otoacoustic emission (TEOAE) is being a non-invasive, objective technique and required less time to get administered can be easily used to find out effect of short duration broad band noise (BBN). However one must know the sensitivity of TEOAEs in predicting susceptibility of noise induced hearing loss. Thus the present study has taken up to find out the effect on TEOAE amplitude because of short duration exposure of BBN. Results indicated that there was statistically significant reduction in amplitude of TEOAE at all frequencies except 1 kHz (p < 0.05). It is also observed that the basal region of cochlea is more prone to noise exposure than apical region as revealed in the outcome of the study.
