Many of the issues associated with the selection of frequency responses for hearing aids are similar to those encountered in the design of voice communication systems for listeners with normal hearing. The design of such systems typically utilizes the predictions of articulation theory, which incorporate the results of a wide variety of measurements of speech transmission under conditions of restricted bandwidth, additive noise, and limited dynamic range. Although a number of investigations has reported that articulation theory can be used successfully to determine the frequency response of hearing aids, it is widely used for this purpose at present. In this paper we examine the extent to which recent studies of the frequency response of hearing aids can be described by articulation theory and also consider the predictions for the optimum frequency response that can be derived from the theory.
