Abstract: A binaural hearing system comprises a first and second hearing aids. The hearing aids each comprises antenna and transceiver circuitry allowing the exchange of audio signals between them. At least one of the hearing aids comprises primary and secondary adaptive 2-channel beamformers each providing a spatially filtered signal based on first and second beamformer-input signals. The primary and secondary 2-channel beamformers are coupled in a cascaded structure. In an embodiment, the spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of user's own voice. In an embodiment, the spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of a target signal in the environment. In an embodiment, the inputs to the secondary 2-channel beamformer may be beamformed signals from the first and second hearing aids respectively.

Abstract: A binaural hearing system comprises first and second hearing aids, each comprising antenna and transceiver circuitry allowing the exchange of audio signals between them and a BTE-part adapted for being located at or behind the external ear (pinna) of the user and comprising front and rear input transducers providing respective front and rear electric input signals. Each of the hearing aids comprises primary and secondary adaptive 2-channel beamformers each providing a spatially filtered signal based on first and second beamformer-input signals. The primary and secondary 2-channel beamformers are coupled in a cascaded structure. The inputs to the primary 2-channel beamformers are, locally generated, front and rear electric input signals. The inputs to the secondary 2-channel beamformer may be beamformed signals from the first and second hearing aids respectively. The spatially filtered signal of the secondary 2-channel beamformer may comprise an estimate of a target signal in the environment of the user.

Abstract: A hearing system comprises a first hearing device, e.g. a hearing aid. The hearing system comprises at least three input transducers, one of which being selected as a reference input transducer providing a reference input signal, at least two adaptive 2-channel beamformers, each providing a spatially filtered signal based on first and second beamformer-input signals, wherein the adaptive 2-channel beamformers maintain unit amplitude and phase for a target component of said reference input signal. The at least two 2-channel beamformers are coupled in a layered structure at least comprising a primary layer and a secondary layer. The adaptive parameter of a given 2-channel beamformer is determined from the first and second beamformer-input signals for the 2-channel beamformer in question.
