Abstract
A method for compensating for acoustic crosstalk between a first and a second microphone unit being acoustically connected to a shared volume. The method includes the steps of providing a first output signal, Pout, from the first microphone unit, providing a second output signal, Uout, from the second microphone unit, and generating a compensated output signal by combining a portion of one of the output signals with the other output signal via addition or subtraction in order to compensate for acoustical crosstalk. The invention further relates to a microphone module configured to implement the before-mentioned method. The invention further relates to a hearing aid comprising the microphone module.
