Abstract :
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.
