DSP 助听器 hearing aids

This application report describes the development of a new low power binaural wearable digital hearing aid platform based on the TMS320C5000E fixed point digital signal processor (DSP).This platform is a real-time system capable of processing two input speech channels at a 32 KHz.sampling rate for each channel and driving a stereo headphone output. It provides for frequency shaping, noise suppression, multiband amplitude compression, and frequency dependent interaural time delay algorithms. Since the platform is a programmable solution capable of running at 1.8 V for MIPS intensive research and 1 V for actual hearing aid implementation, this platform will enable further research into improving the quality of life for the hearing impaired
