Abstract

This paper deals with digital processing of speech as it pertains to the hearing impaired. The issues described in this paper deal with the development of a true real-time digital hearing aid. The system (based on Texas Instruments TMS320C3X) implements frequency shaping, noise reduction, interaural time delay, amplitude compression and various timing options. It also provides a testbed for future development. The device is referred to as the DIgital Programmable Hearing Aid (DIPHA). DIPHA uses a wide bandwidth (up to 16 kHz). DIPHA is a fully programmable device that permits us to program various speech processing algorithms and test them on hearing impaired subjects in the real world as well as in the laboratory
