    Abstract: A binaural hearing aid system includes first and second hearing aids configured to be worn by a user at or in respective first and second ears of the user, each of the first and second hearing aids including: at least one input transducer configured to pick up a sound at the at least one input transducer and to convert the sound to at least one electric input signal representative of the sound, the sound at the at least one input transducer including a mixture of a target signal and noise; a controller for evaluating the sound at the at least one input transducer and providing a control signal indicative of a property of the sound; a transceiver configured to establish a communication link between the first and second hearing aids allowing the exchange of the control signal between the first and second hearing aids; a transmitter for establishing an audio link for transmitting the at least one electric input signal, or a processed version thereof, to another device. The controller is configured to: transmit the locally provided control signal to, and receive a corresponding remotely provided control signal from the opposite hearing aid via the communication link, and to compare the locally provided and the remotely provided control signals and to provide a comparison control signal in dependence thereof, and to transmit the at least one electric input signal, or a processed version thereof, to the another device via the audio link in dependence of the comparison control signal.

    IPC: H04R25/00

    Abstract: A hearing device, e.g. a hearing aid, comprises an input unit; an output unit; an adaptive beamformer filtering unit configured to provide a spatially filtered signal based on a multitude of electric input signals from the input unit and an adaptively updated adaptation factor β; a memory, wherein A) a reference value REF, equal to or dependent on a value, βov, of said adaptation factor β determined when a voice of the user is present, or B) a set of parameters for classification based on logistic regression or a neural network, is stored; and an own voice detector configured to provide an estimate of whether or not, or with what probability, a given input sound originates from the voice of the user, and wherein said estimate is dependent on a) a current value of said adaptation factor β and said reference value REF, or on b) said set of parameters for classification based on logistic regression or a neural network, respectively.
