摘要
耳声发射是常用的听力筛查方法。为了降低成本和开发难度,设计一种基于安卓手机的耳声发射筛查系统。安卓手机控制基于STM32单片机的刺激采集双效卡产生刺激声,再采集耳声信号并传送至手机。安卓应用程序完成数据处理、结果显示、打印等功能。该系统实现了常见的耳声发射筛查,包括瞬态耳声发射、畸变产物耳声发射筛查。
The otoacoustic emission(OAE)is a commonly-used hearing screening method.To reduce the cost and develop-ment difficulty,an OAE screening system based on Android mobile phone was designed.The Android mobile phone controls thestimulation-acquisition dual-task card based on STM32to produce the acoustic stimulation,and then acquire the otoacoustic sig-nal and transmit it to the Android mobile phone.The Android application program can accomplish the functions of data process-ing,result displaying and printing.The system realized the conventional OAE screening,including transient evoked otoacousticemission(TEOAE)and distortion product evoked otoacoustic emission(DPOAE).
