【摘要】：耳聲發(fā)射是常用的聽力篩查方法。為了降低成本和開發(fā)難度,設(shè)計(jì)一種基于安卓手機(jī)的耳聲發(fā)射篩查系統(tǒng)。安卓手機(jī)控制基于STM32單片機(jī)的刺激采集雙效卡產(chǎn)生刺激聲,再采集耳聲信號(hào)并傳送至手機(jī)。安卓應(yīng)用程序完成數(shù)據(jù)處理、結(jié)果顯示、打印等功能。該系統(tǒng)實(shí)現(xiàn)了常見的耳聲發(fā)射篩查,包括瞬態(tài)耳聲發(fā)射、畸變產(chǎn)物耳聲發(fā)射篩查。
[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.
