Design manner of aural signal treatment system for hearing aid, aural signal treatment system, and hearing aid for hearing aid

摘要

You design the hearing aid which is adjusted to the hearing impairment person, making use of sampled-data control theory. The digital filter K for the hearing aid signal processing_c the digital voice input signal which is output from the AD converter and the AD converter which convert the analog voice input signal y to the hearing aid to the digital voice input signal (z) with, the DA converter which is converted to the analog voice response signal in order to output the digital signal which is output from digital filter for the hearing aid, to the hearing impairment person and, being design manner of the aural signal treatment system for the hearing aid which it possesses, filtering doing the analog voice response signal which is output from the DA converter the analog filter P which possesses the property which corresponds to the auditory property of the hearing impairment person (s) by the restoration analog which canIn order_c for error e of analog voice input signal y to_c signal z and_c the hearing aid to become small, digital filter K for the hearing aid (z) you design with sampled-data control theory.
