ABSTRACT
An electroacoustic investigation of aided ILDs and ITDs has been performed using six commercially-available hearing aids that incorporate spatial cue signal processing. The purpose of the study was to measure errors associated with amplification. Two distinct audiograms were tested. When configured according to manufacturers’ recommended procedures, all devices produced ILD errors that varied with azimuth and increased with frequency. ITD errors were also common among products. Results suggest that spatial cue signal processing provided by hearing aids has not been optimized and that more research is needed before conclusions about benefit can be made.
