摘要

针对数字助听器需要实时操作且资源便宜的特点，设计了一种盲源分离系统。此外，我们在数字信号处理器(DSP)上实现了我们的BSS系统，该系统可用于数字助听器设备。这将使音质更好，不同的声源可以根据用户的要求分别放大。我们用降噪率来衡量系统的性能;仿真和实时实现的性能分别为1.4081和1.2137 db。结果表明，BSS系统适用于数字助听器应用，可实现实时操作。

The design of a blind source separation system for digital hearing aids

A blind source separation system is designed for digital hearing aids which required real-time operating and inexpensive resources. In addition, we implement our BSS system on a digital signal processor (DSP) which can be used in digital hearing aid devices. This will enable a better sound quality in which different sound sources can be amplified separately based on the user requirement. We measure the performance of the system by noise reduce rate; the performance of simulation and real-time implementation is 1.4081 and 1.2137 db respectively. The results illustrate that our BSS system is suitable to apply for digital hearing aids application and can be operated in real-time.
