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 18):
A method according to  claim 14  wherein the transfer function H ITE (\u03b8, \u03c6, r, k) of the microphone located close to or in the ear canal, before being used in said predefined criterion, is modified in one or more frequency bands.
