ABSTRACT:
A digital hearing aid having a variable hearing compensating characteristics, comprises a hearing compensating circuit having a transposed transversal filter, an analyzer for frequency-analyzing an input signal, a memory storing a hearing characteristics of a person to be fitted with the hearing aid, and a controller receiving a frequency analysis result of the input signal and the hearing characteristics, for deriving coefficients for the transposed transversal filter to supply the derived coefficients to the transposed transversal filter. Since the transposed transversal filter is used, the S/N ration is improved, and the control of the characteristics of the filter becomes easy.
