Significance of output:

Several million people in the UK suffer from hearing impairment and may benefit from hearing aid provision (Davis,A., 1998). Directional microphones are the only hearing aid noise reduction feature shown to improve the common problem of hearing speech in background noise. However there are no established clinical test methods for microphones. This paper describes a new technique suitable for clinical testing of directional microphones which is robust to effects of non-linearity, which is a common feature of many hearing aids. An important finding, with clinical implication, is that the directional benefit of a hearing aid varies significantly between individuals.
