【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。
[Abstract]:Otoacoustic emission (OAE) is a commonly used method for hearing screening. In order to reduce the cost and development difficulty, an otoacoustic emission screening system based on Android phone is designed. The Android phone controls the stimuli acquisition card based on STM32 single chip computer to produce the stimulation sound, and then collects the ear sound signal and transmits it to the mobile phone. Android applications complete data processing, results display, printing and other functions. The system realizes common otoacoustic emission screening, including transient otoacoustic emission and distortion product otoacoustic emission screening.
