Study the Effect of the Different Stimulation Levels for TEOAEs bythe Non-Linear Models

ABSTRACT In this work, we study the effect of different stimulation levels on TEOAEs in the hearing process using non-linear models for the stimulus levels (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, and 120) dB. We found that the latency as a function to stimulation level, by the results of TEOAEs we get from the different stimulus levels in the relationship of time-frequency. Therefore, relationship of time-frequency is very important in comparison results the different stimulus level with the previous studies and also useful in the study of hearing process in humans. At the analysis of relationship of time-frequency we get a lot of the results that show the characteristics for TEOAEs. From these results obtained in study the effect of different stimulus levels for TEOAEs in the relationship of time-frequency are the energy distribution and waveform behavior of TEOAEs. Energy distribution of TEOAEs shows the pool (concentration) energy in a number of spots (points) and the energy distribution varies from one stimulus level to another. Effect of waveform behavior TEOAEs by different stimulus levels, so latency is as a function to the frequency and the stimulation level.
