Predictive Value of Directional Sensitivity Diagrams of Hearing AIDS for Word Discrimination in Noise
K. T. van der Laan, Hero P. Wit · Scandinavian Audiology · 1983
In an anechoic 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.
