FPGA Implementation of Comb Filter for Audibility Enhancement of Hearing Impaired
Subscribe/Renew Journal
In this paper, FPGA implementation of comb filter required for hearing aids useful for hearing impaired people suffering from sensorineural hearing loss has been proposed. The difficulties in algorithm implementation on FPGA based hardware is the complexity involved during design and it implementation. Here, a new approach has been used to implement comb filter on FPGA platform. This work describes the hardware miniaturization of the hearing aid system.
