A hearing aid device is disclosed. The hearing aid device comprises means to improve, augment and/or protect the hearing capability of a user by receiving acoustic signals from the surroundings of the user, generating corresponding audio signals, possibly modifying the audio signals and providing the possibly modified audio signals as audible signals to at least one of the user's ears. The hearing aid device comprises a sensor member for detecting the movement and/or acceleration and/or orientation (or spatial position) of the hearing aid device. The hearing aid device comprises at least two hearing aid microphones and a control unit for determining the position or a deviation from an intended position of the hearing aid device or hearing aid microphones. The hearing aid device is configured to compensate for a possible dislocation of the hearing aid microphones.

Hearing aid device comprising a sensor member

A hearing aid and a method performed by a hearing aid including at least one microphone unit, an accelerometer unit, and a processor. The method performed by the hearing aid includes generating a processed microphone signal including attenuating the microphone signal in accordance with an attenuation value; wherein the attenuation value is based on a measure of correlation between a microphone signal from the microphone unit and an acceleration signal from the accelerometer unit. The hearing aid instantly reduces noise arising from mechanical handling of the hearing aid based on input from the microphone unit and the accelerometer unit.

Hearing aid having a sensor

A hearing aid comprises a) first and second microphones b) an adaptive beamformer filtering unit comprising, b1) a memory comprising a first and second sets of complex frequency dependent weighting parameters representing a first and second beam patterns, b3) an adaptive beamformer processing unit providing an adaptation parameter &#x3b2;(k) representing an adaptive beam pattern, b4) a memory comprising a fixed adaptation parameter &#x3b2;(k) representing a third, fixed beam pattern, b5) a mixing unit providing a resulting complex, frequency dependent adaptation parameter &#x3b2;(k) as a combination of said fixed and adaptively determined frequency dependent adaptation parameters &#x3b2;(k) and &#x3b2;(k), respectively, and b6) a resulting beamformer (Y) for providing a resulting beamformed signal Ybased on first and second microphone signals, said first and second sets of complex frequency dependent weighting parameters, and said resulting complex, frequency dependent adaptation parameter &#x3b2;(k).

Hearing device comprising a beamformer filtering unit

A hearing aid comprises a) first and second microphones b) an adaptive beamformer filtering unit comprising, b1) a first and second memories comprising a first and second sets of complex frequency dependent weighting parameters representing a first and second beam patterns, where said first and second sets of weighting parameters are predetermined initial values or values updated during operation of the hearing aid, b3) an adaptive beamformer processing unit providing an adaptation parameter &#x3b2;(k) representing an adaptive beam pattern configured to attenuate unwanted noise under the constraint that sound from a target direction is essentially unaltered, b4) a third memory comprising a fixed adaptation parameter &#x3b2;(k) representing a third, fixed beam pattern, b5) a mixing unit providing a resulting complex, frequency dependent adaptation parameter &#x3b2;(k) as a combination of said fixed and adaptively determined frequency dependent adaptation parameters &#x3b2;(k) and &#x3b2;(k), respectively, and b6) a resulting beamformer (Y) for providing a resulting beamformed signal Ybased on first and second microphone signals, said first and second sets of complex frequency dependent weighting parameters, and said resulting complex, frequency dependent adaptation parameter &#x3b2;(k).

The application relates to a hearing assistance device adapted for being located in or at a specific one of a left or a right ear of a user, and comprising an input unit for receiving an input signal and an output unit for providing an output signal. The application further relates to a method and to a hearing assistance system. The application aims at providing an improved scheme for detecting left/right placement of a hearing device. The hearing assistance device further comprises a memory unit wherein information about the intended location of the hearing assistance device is or can be stored, a location identification unit configured to extract an intended location from said memory unit, and a user interface configured to convey information related to the intended and/or current location of the hearing assistance device. A user is thus informed, if the hearing assistance device(s) is/are not located as intended.
