Objective: In order to provide grounds for clinical diagnosis, the normal sensitive parameters of the transient evoked otoacoustic emissions (TEOAE) in normal ears were studied.
Method: 60 ears with normal hearing subjects using ILO-88 otodynamic analyzer system were measured, the click stimuli level is 80 dB SPL and the stimuli pattern used non-linear model.
Result: Analysis of the normal values of the stability, A-B difference, response amplitude, wave reproducibility, band reproducibility and band SNR, dominant frequencies were obtained.
Conclusion: The findings from comprehensive analysis of spectrum, response amplitude and reproducibility can be used as main sensitive parameters to evaluated whether or not of normal-hearing.
