Abstract
In an anchoic room the directional characteristics of 17 different hearing aids were evaluated using KEMAR Word discrimination scores in the presence of speech-like masking noise—a reliable parameter for the performance of a hearing aid—were compared with the directional sensitivity of the hearing aid under study for different signals. The directional characteristics of a hearing aid have the best predictive value for word discrimination scores in the presence of masking noise if this masking noise is used to measure these characteristics.
