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 BTEi (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 i (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 H pinna (θ, φ,  r, k )=Σ i=1 M W i ( k )· H BTEi (θ, φ,  r, k ), so that a difference between the resulting transfer function H pinna (θ, φ, r, k) and a transfer function H ITE (θ, φ, r, k) of a microphone located close to or in the ear canal fulfils a predefined criterion.

Claim (Index 9):
A hearing aid according to  claim 8  wherein said weighting function is adaptively determined in dependence of an acoustic environment.
