Abstract

First developments in digital processing of speech sound were done in 1960s in Bell Laboratories. In recent years the use of digital components in the design of hearing aids (HAs) is fast becoming a standard rather than an exception. Various HAs on the market, that utilize digital circuits, have proven to provide increased flexibility and efficiency in both fitting and hearing aid evaluation. Although the availability of digital signal processing (DSP) techniques that are applied to the incoming signal do not vary much in the commercially available units, it is evident that research in DSP is the most promising area in future hearing aid development. Already new generation of HAs brings higher levels of satisfaction from the end user-hearing impaired. The authors give a description of the major DSP types that are on the market
