【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。更多还原

【Abstract】 The otoacoustic emission(OAE)is a commonly-used hearing screening method. To reduce the cost and development difficulty,an OAE screening system based on Android mobile phone was designed. The Android mobile phone controls the stimulation-acquisition dual-task card based on STM32 to produce the acoustic stimulation,and then acquire the otoacoustic signal and transmit it to the Android mobile phone. The Android application program can accomplish the functions of data processing,result displaying and printing. The system realized the conventional OAE screening,including transient evoked otoacoustic emission(TEOAE)and distortion product evoked otoacoustic emission(DPOAE).更多还原
