Research Abstract

This research aims to study new methodologies to develop next-generation highperformance binaural hearing aids with general versatility. Far-sighted glasses forelderly can be obtained at the cost from 10,000 or so, but a pair of inner canal typedigital hearing aids costs more than 10 times of glasses. Due to this price issue, thehearing aids are not popular even if the necessity and demand form elderly are clear.Thus we would like to have an “universal” hearing aids which are easy to use and easyto get, Based on this concept, we have studies the basic methods to develop an universalbinaural hearing aids with a versatility and high performance on special selectivity andhowling prevention.
