An Update on the Directional Hearing Aid Test System

By Neuman, Arlene, PhD; RERC-HE Newsletter, Vol. 8, No. 1, p. 2
Publication Date: Spring 2003

Article describes the Directional Hearing Aid Test System, which was developed at the Rehabilitation Engineering Research Center (RERC) on Hearing Enhancement. The system consists of a personal computer with an array of loudspeakers, for presenting signals from an array of directions. The system allows for the measurement of the directivity pattern of a hearing aid from 32 different angles by having the client sit in the center of an array of loudspeakers. The Directional Hearing Aid Test System shows the effects of placing the hearing aid in the ear of the user where the head and body, as well as the location of the hearing aid are taken into account. At the time the article was written, professionals at the RERC were using the test system to measure the characteristics of directional hearing aids on current hearing aid users.
