Abstract
A microphone module includes a first MEMS microphone and a second MEMS microphone, wherein the first MEMS microphone includes a first modulator, and wherein the second MEMS microphone includes a second modulator. For the purpose of noise reduction, a defined offset can be applied to an input of the first modulator or of the second modulator. Alternatively, for the purpose of noise reduction, the first modulator and the second modulator can be operated with different modulation frequencies.
