Abstract

A hearing aid includes: a feedback monitor connected to the adaptive feedback canceller and configured to monitor a state of feedback and having an output providing an indication of the state of feedback; and a cue controller connected to the feedback monitor and the at least one adaptive cue filter, and configured to control, in response to an output of the feedback monitor, the at least one adaptive cue filter so that the difference between the output of the at least one ITE microphone and the combined output of the at least one adaptive cue filter is reduced.

Description

technical field [0001] A new type of hearing aid is provided with improved sound source localization relative to the wearer of the hearing aid. Background technique [0002] It has been reported that hearing aid users have a poorer ability to localize sound sources when wearing their hearing aids than when not wearing their hearing aids. This represents a serious problem for people with mild to moderate hearing impairment. [0003] Furthermore, hearing aids typically reproduce sounds in such a way that the user perceives the sound source as being localized inside the head. Sound is described as internalized rather than externalized. A common complaint among hearing aid users when referring to "hearing speech in noise problems" is that it is difficult to keep up with whatever is being said, even though the signal-to-noise ratio (SNR) should adequately provide the desired speech intelligibility . An important reason for this fact is that the hearing aid reproduces the inte...
