多通道皮肤听声器质量检测系统的研究

Researches on Quality Detection System of Multi-Channel-Array Skin-Hearing

多通道皮肤听声器是目前最新的助听设备。通道数目的增加提高了语音的辨析能力,但同时也使皮肤听声器的结构变得复杂。使其在制作过程中会出现很多问题,导致各通道间信号相互影响,从而使得皮肤对于语音信号的辨析能力大大降低。同时以往的检测都是人为进行,效率很低。针对上述问题,提出了基于DSP的数字化并行检测方法,并且将数字内插的方法运用其中以实现信号波形的重建。实验主要介绍多通道并行检测的硬件,软件实现方案,波形重建的算法。实现质量检测的功能。

At present, Multi--Channel Array Skin Hearing aid is the latest assistive listening devices. Multi--Channel--Array not only improve the speech discrimination ability, but also makes the structure of skin--hearing aid becomes complicated. There will be a lot of errors in the making process of skin--hearing aid, leading to the interaction of each channel signal, which makes the voice discrimination ca- pability of skin reduce greatly. Meanwhile, the conventional detection methods are performed manually, the efficiency is very low. To resolve the problem, this paper proposed a parallel detection method Based on DSP digital. Also it used the digital interpolation to reconstruct the signal waveform. Experiment introduces the multi--channel parallel detection of hardware, software implementation, wave--reconstructing algorithm. Achieve quality testing function.
