Objective:To explore clinic using value of transient evoked otoacoustic emissions (TEOAE) by measuring normal values of TEOAE.Methods:40 ears of young subjects with normal hear were measured by using ILO 96 otodynamic analyzer system.The click stimuli level is 80 dB SPL and the stimuli pattern is non linear model.Result:A&B mean,A B difference,response amplitude,wave reproducibility are 5 6~22 2,-2 1~5 5,4 5~18 9 dB SPL,and 66 7~100% respectively.Band reproducililities and SNR of 1000,1500,2000,3000,4000 Hz are 40 1%~100%,70 4%~100%,59 8%~100%,59 7%~100%,41 5%~100% and 0 0~20 8,2 2~26 2,-2 3~22 5,-2 1~23 1,-3 8~20 2 dB SPL respectively.TEOAE powen analysis half octave values are -20 8~-2 4,-10 5~-3 5,-6 3~12 1,-4 4~14 4,-6 9~12 7,-8 8~14 6,-8 2~12 6,-26 5~-5 3,-29 3~-10 9 dB SPL respectively.Conclusion:Measuring data of response amplitude and wave reproducibility can reflect the living sate of cochlea.Measuring data of band reproducibility,band SNR,and TEOAE power analysis can reflect the living state of every part of cochlea.
