Optimal hearing aid processing characterization and device adaptation characteristics hearing aids

摘要

PROBLEM TO BE SOLVED: To provide an adaptive characteristic hearing aid, in which hearing aid processing characteristics are determined for adaption to environmental sounds. ;SOLUTION: The adaptive characteristic hearing aid comprises a hearing aid signal processing section 2 for signal processing an inputted acoustic signal into a sound adapted to a hard of hearing user, on the basis of signal processing characteristics determined by fitting parameters provided from the outside, an acoustic parameter extracting section 3 for extracting acoustic parameters from the inputted acoustic signal, and an adaptive hearing aid processing characteristic determining section 4 for determining characteristics of the section 2, in accordance with the acoustic parameters obtained from the section 3. The section 4 consists of a mapping section 41 for describing a mapping relation for converting the acoustic parameters into fitting parameters.;COPYRIGHT: (C)2003,JPO
