Myths About Hearing in Noise and Directional Microphones

By Killion, Mead C., PhD; Hearing Review, Vol. 11, No. 2, pp. 14-19, 72-73
Publication Date: February 2004

Article discusses the use of directional microphones in hearing aids, which are only utilized in roughly 20 to 30 percent of hearing aids. One reason for this is that as few as eight percent of dispensing professionals have access to the QuickSIN or HINT tests, which evaluate hearing in noise. Even fewer realize that half of their clients face a five-decibel signal-to-noise ratio hearing loss. Some directional systems offer relatively low improvement in noise, which is important in the long run, yet not immediately noticeable by most clients. Myths about the use of directional microphones are discussed and debunked, while implications for further studies are introduced.
