A FULLY INTEGRATED DIGITAL HEARING AID WITH HUMAN EXTERNAL CANAL CONSIDERATIONS

摘要

PROBLEM TO BE SOLVED: To provide a digital hearing aid adjusted for human's outer ear structure.;SOLUTION: Outer ear structures with sizes and morphologic appearances varying from individual to individual are modeled to obtain resonance gains due to structural features before digitalizing them such that they can be used for gain factors of the digital hearing aids for signal processing and apply to a digital signal processing part. A gain acquisition unit 200, in consideration of resonance gains due to the structural features and gains acquired through hearing test at the same time, reduces gain correction time periods and possible errors while optimizing individual performances.;COPYRIGHT: (C)2008,JPO&INPIT
