AI Technical Summary

Problems solved by technology

[0003] 1) hearing loss, which is an increase in hearing threshold level, and
[0004] 2) Loss of ability to understand speech in noise compared to normal hearing individuals
An important contributor to this situation is that the hearing aid reproduces an internalized sound field, which increases the recognition load for the hearing aid user and can lead to listening fatigue and eventually the user taking off the hearing aid

Embodiment Construction

[0096] The new method and binaural hearing aid system will now be described more fully with reference to the following drawings, in which various examples of the new binaural hearing aid system are illustrated. However, the new method and binaural hearing aid system may be embodied in different forms and should not be construed as limited to the examples given here. Rather, these examples are provided so that this disclosure will be thorough and complete, and will convey the scope of the invention to those skilled in the art.

[0097] It should be noted that the drawings are schematic and simplified for clarity and that they only show details necessary for the understanding of the invention, while other details are omitted.

[0098] Like reference numerals refer to like elements throughout. Similar elements will therefore not be described in detail with respect to the description of each figure.

Abstract

A new binaural hearing aid system is provided with a hearing aid in which signals that are received from external devices, such as a spouse microphone, a media player, a hearing loop system, a teleconference system, a radio, a TV, a telephone, a device with an alarm, etc., are filtered with binaural filters in such a way that a user perceives the signals to be emitted by respective sound sources positioned in different spatial positions in the sound environment of the user, whereby improved spatial separation of the different sound sources is facilitated.

Description

technical field [0001] A new binaural hearing aid system configured to impose a perceived spatial separation for a monaural signal source is provided. Background technique [0002] Hearing-impaired individuals often experience at least two distinct problems: [0003] 1) hearing loss, which is an increase in hearing threshold level, and [0004] 2) Loss of ability to understand speech in noise compared to normal hearing individuals. Most hearing-impaired patients perform worse than normal-hearing people on tests of intelligibility of speech in noise, even when audibility of incoming sounds is restored by amplification. The Speech Reception Threshold (SRT) is a performance measure for the loss of the ability to understand speech and is defined as the required value in the presented signal to achieve an aurally correct word recognition of 50% in the noise test. SNR. [0005] To compensate for hearing loss, today's digital hearing aids typically use multi-channel amplificati...
