Embodiment Construction

[0102] figure 1 An example of the new binaural hearing aid 10 is schematically illustrated that operates to enhance a target signal by exploiting the ability of the human auditory system to focus on the target signal.

[0103] In the new hearing aid 10 shown, speech intelligibility is improved by outputting a target signal and a masking signal in different frequency bands to the ear drums of a user of the binaural hearing aid.

[0104] In this way, energy masking caused by simultaneous presentation of the target signal and the masker signal is reduced by separating the signal into different frequency bands.

[0105] It has been shown that for speech as the target signal and Gaussian noise as the masker signal, an SRT improvement of 15 dB can be obtained for listeners with normal hearing and approximately 10 dB for hearing impaired listeners.

[0106] This improvement is obtained without removing part of the signal; rather, the target and masking signals are presented to the u...

Abstract

This invention discloses a frequency-no-masking hearing aid for ears. The novel double-ear hearing aid uses a new method to compensate the comprehension of a hearing-impaired user in noise. The novel method comprises steps of providing at least microphone audio frequency signal (18,20) by responding to the sound; and providing at least one evaluation of evaluations of object signal (26) and noise signals (30) based on at least one microphone audio frequency signal (18,20). At least one of the evaluations of the object signals (26) and the noise signals (30) is modified by the following methods of modifying the evaluation of the object signal (26) and the evaluation of the noise signal (30) which are positioned within different frequency bands; sending an evaluation of modified the object signal to the drumhead of the user of the double-ear hearing aid (10); and sending another modified evaluation of the noise signal of the drumhead of the user.

Description

technical field [0001] A new binaural hearing aid system is provided that compensates for the loss of hearing-impaired users' ability to understand speech in noise. Background technique [0002] Hearing-impaired individuals often experience at least two distinct problems: hearing loss, which is an increase in the threshold level of hearing; and impairment of the ability to understand speech at high levels in noise compared to normal-hearing individuals. lost. Most hearing-impaired patients perform worse than normal-hearing individuals on tests of speech intelligibility in noise, even with amplification to restore the audibility of incoming sounds. An individual's Speech Reception Threshold (SRT) is the signal-to-noise ratio required in the presented signal to obtain 50% correct word recognition in an auditory test in noise. [0003] Today's digital hearing aids, which use multi-channel amplification and compression signal processing, can easily restore the audibility of am...
