Problems solved by technology

[0005] This is a known issue and upcoming binaural hearing aid systems, i.e. hearing aid systems comprising two hearing aid units communicating with each other via a wired or wireless connection, allow for binaural processing, i.e. collaborative audio processing in both hearing aid units , thus allowing the reduction of the above ILD to weaken the

Embodiment Construction

[0021] figure 1 The binaural hearing aid system 1 shown in FIG. 2 comprises two hearing aids 2 , 3 respectively located at the left ear 4 and right ear 5 of a hearing aid user 6 , and the two hearing aids are interconnected by a wireless communication channel 7 . The first person 8 is located in front of the user 6 . The second person 9 and the truck 10 are located to the left of the user 6 . The third person 11 is located to the right of the user 6 .

[0022] In the following description of the binaural hearing aid system 1 and hearing aids 2, 3, the term "local" refers to components, characteristics, signals, etc. of the particular hearing aid 2 or 3 currently being described, while the term "remote" refers to the other hearing aid 2 or 3 of these entities. The same applies to ears 4,5.

[0023] To simplify the following description, it is assumed that the hearing aids 2, 3 are identical, and as figure 2 As shown in , each of them includes a microphone 12, an analog-to...

Abstract

The invention provides a method for controlling a binaural hearing aid system and a binaural hearing aid system. Level compression applied to the acoustic signals (18) received by a binaural hearing aid system (1) counteracts the preservation of inter-aural level differences (ILD) and thereby reduces the user's ability to locate the sound source and consequently his or her ability to understand speech in noisy environments. It is therefore known to increase the gain (57) in the hearing aid (2) receiving the louder signal and / or decreasing the gain (58) in the hearing aid (3) receiving the quieter signal, which at least in part allows for preserving the ILDs. However, in some situations this instead reduces the user's ability to understand speech, e.g. when acoustic noise is received at one ear (4) at a higher level (53, 54) than simultaneous speech at the other ear (5). The present invention overcomes this problem by decreasing the gain (57) in the hearing aid (2) receiving the louder signal and / or increasing the gain (58) in the hearing aid (3) receiving the quieter signal, when the difference between the noise-floor levels (55, 56) of the two hearing aids (2, 3) increases.

Description

technical field [0001] The invention relates to a method for controlling a binaural hearing aid system and a binaural hearing aid system. More specifically, the present invention relates to a method for controlling acoustic gain in a hearing aid system that receives an acoustic signal from an individual's surroundings, performs binaural processing on the acoustic signal, and provides the processed signal to the individual's ears, And it relates to a hearing aid system adapted to perform the method. [0002] The invention may be used, for example, in applications such as compensating for the loss of hearing ability of hearing impaired individuals or enhancing the hearing ability of normal hearing individuals. Background technique [0003] The main purpose of a hearing aid is usually to amplify received acoustic signals so that they can be heard by the hearing aid user. To keep the amplified signal within the user's "comfortable dynamic range," the range of amplitudes betwee...
