基于Android移动平台的单双通道助听器实现

Single and dual-channel hearing aids based on Android mobile platform

为了在嘈杂环境下给弱听患者提供更好的助听效果,设计了一种基于Android移动平台的单、双通道助听器应用。该助听器通过Android系统提供的音频组件调用设备的麦克风进行数据采集并缓存,利用单、双通道语音增强算法对缓存的数据进行处理并送入相应音频组件进行播放。测试结果表明,在Android移动平台通过单、双通道消噪功能可从移动设备耳机听到清晰的增强后语音,实现对环境噪声的良好滤除。

In order to provide better hearing effect for the hearing patients in a noisy environment, a single and dual-channel hearing aids based on Android mobile platform was designed. The audio module of Android system was utilized to invoke and cache the speech data from microphone, and then the speech data was sent to the audio module after processing with the single and dual-channel algorithm. The test results show that user can hear clearly enhanced speech from the headset through the signal and dual-channel noise cancellation function, the noise is eliminated effectively.
