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.
