Analysis of the influence factors of otoacoustic emission of real human bone conduction
Based on the two-tone suppression principle,the measurement of otoacoustic emission of real human bone conduction is studied based on the stimulus frequency otoacoustic emission(SFOAE)signal with four interval method,so as to analyze the influencing factors of otoacoustic emission in real human bone conduction.The SFOAE signals were measured in ten subjects with normal hearing.The experimental results show that the SFOAE signals measured at different stimulus intensities are different,and they increase linearly with the increasing of the stimulus intensities within the experimental intensity range;the trends of SFOAE signals measured under different stimulus durations are similar;the SFOAE signals at the mastoid and condyle are similar,and the SFOAE signals at the temple are different from the other two positions.In this paper,the influencing factors of the SFOAE signal are explored and analyzed,which can provide a theoretical basis for the study of bone conduction physiological characteristics,transcranial attenuation,crosstalk cancellation and response compensation.
