Abstract

Providing a portable, high-precision audiometry system based on adaptive sound field compensation. [Solution] The system includes an environmental monitoring module used to acquire an environmental noise signal; an audiometry monitoring module used to acquire an audio test signal and user feedback information; a data transmission module used to set environmental transmission channel protocols and test transmission channel protocols corresponding to the data processing terminal for the environmental end and the test detection end, respectively, and to transmit the corresponding data information; an environmental compensation module used to perform adaptive sound field compensation based on the environmental noise signal and acquire an initial audio test signal; a test compensation module used to acquire an integrated audio test signal; and a detection analysis module used to acquire the corresponding audiometry data.
