Abstract
A method for calibrating a microphone that includes a transducer element and an ASIC. The method includes calibrating the frequency characteristic of the ASIC such that the sensitivity (S(f)) of the microphone at a predetermined cutoff frequency (f) shows a predefined reduction (Δ) compared to the sensitivity (S(f)) of the microphone at a standard frequency (f). Another aspect of the present invention concerns a microphone.
