Abstract

Disclosed is a method and system for allowing a recipient of a hearing aid device, and in one aspect, a bilateral hearing aid system, to locate the source of a sound signal about the recipient. The method uses localization cues in the sound signal and modifies these to provide useable localization cues to generate a stimulating signal for application to the recipient. In one example, a detected localization cue such as an interaural level difference (ILD) is transposed to a lower frequency.
