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 ILO88 otodynamic analyzer system were measured,the click stimuli level is 80 dB SPL and the stimuli pattern used nonlinear model. Result: Analysis of the normal values of the stability,AB 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 normalhearing.
