With ILO-92 Otodynamics Analyzer,distortion product otoacoustic emissionsat 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.

The contour map is the easiest to distinguish the height of the terrain. According to the study, it demonstrated that the contour map has to be understudied by learning.But there have not suitable teaching materials to supply learning. However, the conventional map is restricted on the paper; the real world must be displayed by usingthe two-dimension. From this research, using the olography in order to get observe the terrain of stereoscopic vision and analyze the geology.
