The method is for designing an audio signal processing system for a hearing aid, wherein the system comprises an AD converter for converting an analog audio input signal (yc) inputted to the hearing aid into a digital audio input signal, a hearing aid digital filter (K(z)) for performing a signal processing on the digital audio input signal outputted from the AD converter, and a DA converter for converting a digital signal outputted from the hearing aid digital filter into an analog audio output signal to be outputted to the hard-of-hearing person. The hearing aid digital filter (K(z)) is designed according to sampled-data control theory so as to reduce an error (ec) occurring between: a restored analog signal (zc) obtained from filtering the analog audio output signal outputted from the DA converter through an analog filter (P(s)) that has characteristics corresponding to auditory characteristics of the hard-of-hearing person; and the analog audio signal (yc) inputted to the hearing aid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for designing audio signal processing system for hearing aid, audio signal processing system for hearing aid, and hearing aid","description":"A hearing aid tailored to a hard-of-hearing person is designed using sampled-data control theory.
