A study on the effects of contralateral acoustic suppression to transient evoked otoacoustic emissions after noise exposure


, : A study on the effects of contralateral acoustic suppression to transient evoked otoacoustic emissions after noise exposure. Lin Chuang Er Bi Yan Hou Ke Za Zhi 16(4): 164-5, 168

To investigate the effects of contralateral acoustic suppression(CAS) on transient evoked otoacoustic emissions(TEOAE) in Noise Exposure Condition, in order to explore the effects of efferent positive feedback regulation on the cochlear mechanisms and the effects of CAS on the sensitivity of TEOAE measure for finding changes of cochlear function condition induced by noise exposure. Observing the effects of CAS (60 dB SPL WN) on the changes of TEOAE parameters, Response Amplitude, Reproducibility, Band SNR and Band Reproducibility, before and after noise exposure. The values of every index of TEOAE were decreased respectively so that the effects of noise exposure on cochlear function can be reflected sensitively. A small decrease of values can be induced by CAS before noise exposure, of some decrease of indices were significant. After noise exposure, the changes of TEOAE parameters become much more with CAS than without. Noise exposure can effect obviously cochlear function condition and decrease OAE measurement values. CAS had suppressing action on cochlear activity by a negative feedback and can increase obviously the sensitivity of TEOAE measurement in finding the changes induced by noise exposure.
