Abstract

The present invention relates to a method of performing bilateral dynamic range compression on first and second microphone signals generated by a first hearing aid and a second hearing aid, respectively, of a binaural hearing aid system, comprising: picking up, by a first microphone, a sound pressure within an ear canal of a left or right ear of a user to generate a first microphone signal in response to incoming sound, and picking up, by a second microphone, sound pressure within the ear canal of the opposite ear of the user to generate a second microphone signal in response to the incoming sound.

Description

technical field

[0001] The present invention relates to a method of performing bilateral dynamic range compression on first and second microphone signals, respectively generated by first and second hearing aids of a binaural hearing aid system. The method includes picking up or receiving, with a first microphone, sound pressure within the ear canal of the user's left or right ear to generate a first microphone signal in response to incoming sound, and picking up or receiving sound within the ear canal of the user's contralateral ear with a second microphone pressure to generate a second microphone signal in response to the incoming sound. Background technique

[0002] People with normal hearing selectively focus on the desired sound source, such as the target speaker, to achieve speech intelligibility and maintain situational awareness in noisy listening conditions, such as restaurants, bars, concert venues, etc. The latter are often named cocktail scenes or sound environme...

Embodiment Construction

[0088] Various exemplary embodiments of the binaural hearing aid system of the present invention are described below with reference to the accompanying drawings. Those skilled in the art will appreciate that the drawings are schematic and simplified for the sake of clarity, and thus only show details essential to the understanding of the invention, while other details are omitted. The same reference numbers refer to the same elements throughout. Therefore, the same elements will not necessarily be described in detail with respect to each drawing.

[0089] figure 1 An exemplary binaural or bilateral hearing aid system 50 is schematically shown comprising first or A left ear hearing aid or instrument 10L and a second or right hearing aid or instrument 10R. The left ear hearing aid 10L includes a first wireless communication interface 34L coupled to the first digital processor 24L and the first antenna 44L. The first antenna 44L may be a radio or magnetic induction antenna. ...
