纯音听损测试系统的Android实现

Android Implementation of Pure Tone Hearing Loss Testing System

基于纯音测听法在Android平台上设计了听力损失测试系统,采用录音方法实现了环境噪音检测,并根据设定正弦波的频率和幅度,生成指定频率和声强的纯音进行双耳的听力检测,并绘制出用户的听力图。经测试,该系统人机交互界面良好,测试结果准确。

A hearing loss test system was designed on Android platform by pure tone audiometry. The environmental noise detection was realized by recording method. According to the frequency and amplitude of sinusoidal wave, the pure tone of specified frequency and sound intensity was generated for binaural hearing detection, and the user's audiogram was drawn. After testing, the system had a good man-machine interface and the test results were accurate.
