Abstract
A hearing aid comprises a BTE-part adapted for being located behind an ear (ear) of a user, and comprising a) a multitude M of microphones, which—when located behind the ear of the user—are characterized by respective transfer functions, H(θ, φ, r, k), representative of propagation of sound from sound sources S to the respective microphones b) a memory unit comprising complex, frequency dependent constants W(k)', i=1, . . . , M, c) a beamformer filtering unit for providing a beamformed signal Y as a weighted combination of the microphone signals using said complex, frequency dependent constants The frequency dependent constants are determined to provide a resulting transfer function(θ,φ,)=Σ()·(θ,φ,),so that a difference between the resulting transfer function H(θ, φ, r, k) and a transfer function H(θ, φ, r, k) of a microphone located close to or in the ear canal fulfills a predefined criterion.
