Embodiment Construction

[0139] Now, hereinafter, the present invention will be described more fully with reference to the accompanying drawings showing exemplary embodiments of the invention. However, this invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals refer to the same elements throughout, and therefore, a detailed description will not be made with respect to the illustration of each figure.

[0140] Figure 4 A hearing aid 10 is schematically illustrated comprising a BTE hearing aid housing 12 (not shown - outer walls removed to make internal structures visible) to be worn behind the user's pinna 100 . BTE housing 12 houses at least one BTE sound input transducer 14, 16 with front microphone 14 and rear microphone 16 for conver...

Abstract

The present invention relates to spatial cues and feedback, and provides a hearing aid comprising: a cue filter having an input provided with an output from a BTE sound input transducer; an adaptive feedback canceller, the adaptive feedback The canceller is configured to provide an output simulating a feedback path between the output transducer and the BTE sound input transducer, wherein the output simulating the feedback path is provided to the subtractor for conversion from the BTE sound input to The output of the feedback path is subtracted from the output of the feedback path to obtain a difference, and the subtractor outputs the difference to the cue filter; and a feedback and cue controller, which is connected to the adaptive feedback canceller and the cue controller. A cue filter, wherein the feedback and cue controller is configured to control the cue filter so as to reduce the difference between the output of the ITE microphone and the combined output obtained using at least the cue filter.

Description

technical field [0001] A novel hearing aid is provided with improved localization of sound sources in relation to a wearer of the hearing aid. Background technique [0002] It has been reported that hearing aid users have a worse ability to localize sound sources when wearing their hearing aids than without hearing aids. This represents a serious problem for the mild to moderate hearing impaired population. [0003] Furthermore, hearing aids typically reproduce sound in such a way that the user perceives a sound source localized in the head. Said voice is internalized rather than externalized. A common complaint among hearing aid users when it comes to "listening to speech noise problems" is that it is very difficult to keep up with what is being said, even though the signal-to-noise ratio (SNR) should be sufficient to provide the required speech intelligibility. An important reason for this fact is that hearing aids reproduce the inner sound field. This increases the co...
