The authors implemented an FPGA-based digital hearing aid which employs a multiband compression system algorithm, which proposed that compression is applied separately in two or more frequency bands. The design was carried out using Verilog VHDL and the implementation was based on the FPGA development board. They studied and profiled the speech processing algorithm implemented in the software version and designed a highly-parallel architecture. The digital hearing aid is useful to overcome all the limitations of analog hearing aid.
