| Abstract: | With ILO-92 Otodynamics Analyzer, distortion product otoacoustic emissions (DPOAEs)at the 2 f1-f2 frequency were recorded from 86 normally hearing ears in response to four groups of different primary levels (L1 = L2 = 75 dB SPL; L1 = L2 = 65 dB SPL; L1 = L2 = 60 dB SPL ;L1 = 65 dB SPL,L2 = 50 dB SPL). The average DPOAEs-gram demonstrated a bilobed contour with two peaks at approximately 1. 5 kHz and 5 kHz and a "notch" between 2. 5 kHz and 3 kHz. Moreover,the contour of DPOAEs-gram had no obvious changes with sex,ear or primary stimulus levels differences. While the primary levels increased, the amplitude of DPOAEs gradua1ly increased,which was about 55~65 dB SPL below the primary levels. At each frequency from 1~6 kHz,statistical analysis showed that there existed significantly different DPOAEs level under four groups of different prirnary stimulus levels. |
