Abstract
The present invention regards a hearing aid device at least one environment sound input, a wireless sound input, an output transducer, electric circuitry, a transmitter unit, and a dedicated beamformer-noise-reduction-system. The hearing aid device is configured to be worn in or at an ear of a user. The at least one environment sound input is configured to receive sound and to generate electrical sound signals representing sound. The wireless sound input is configured to receive wireless sound signals. The output transducer is configured to stimulate hearing of the hearing aid device user. The transmitter unit is configured to transmit signals representing sound and/or voice. The dedicated beamformer-noise-reduction-system is configured to retrieve a user voice signal representing the voice of a user from the electrical sound signals. The wireless sound input is configured to be wirelessly connected to a communication device and to receive wireless sound signals from the communication device. The transmitter unit is configured to be wirelessly connected to the communication device and to transmit the user voice signal to the communication device.

19. A method for processing sound from the environment and a wireless sound signal comprising the steps:
-
receiving sound and generating electrical sound signals representing sound, determining if a wireless sound signal is received, activating a first processing scheme if a wireless sound signal is received, wherein the first processing scheme comprises the steps; using the electrical sound signals to update a noise signal representing noise used for noise reduction, using the noise signal to update values of predetermined spatial direction or transfer function parameters, and activating a second processing scheme if no wireless sound signal is received, wherein the second processing scheme comprises the steps; determining if the electrical sound signals comprise a voice signal representing voice, activating the first processing scheme if a voice signal is absent in the electrical sound signals, and activating a noise reduction scheme if the electrical sound signals comprise a voice signal, wherein the noise reduction scheme comprises the steps; using the electrical sound signals to update the values of the predetermined spatial direction or transfer function parameters, retrieving a user voice signal representing the user voice from the electrical sound signals, wherein a spatial sound signal representing spatial sound is generated from the electrical sound signals using the predetermined spatial direction or transfer function parameters, and a user voice signal is generated from the spatial sound signal using the noise signal to reduce noise in the spatial sound signal. - View Dependent Claims (20)
