Abstract:
Transient Evoked otoacoustic emissions(TEOAE) in 25 hearing- normal youngers was analysed to study its basic character and the influences of different stimulus intensities on the amplitude and the power spectrum which may be useful to identify the hearing-loss subjects as the standardline. We find that the average amplitude of TEOAE is 5.97, 9.22, 12. 76 dB SPL under three intensities,the frequencies of the spectrum distribute from 0 to 6 000 Hz. The two maximal values are located in 1 025 Hz and 1 513 Hz seper-ately. The amplitude of TEOAE increases with the stimulus tone's growth. We conclude that it's necessary to consider completely when evaluating the patient's hearing function by TEOAE's power spectrum on account of its incontinuity and decrease in high frequency.
