Abstract: A microphone and a method for operating a Microphone are disclosed. In an embodiment the microphone includes a transducer and a mode controller. The microphone has a normal operating mode (MO) and a collapse mode (M1). The mode controller switches to the collapse mode (M1) when an output signal of the transducer reaches or exceeds a predefined threshold value and switches to the normal operating mode (MO) when the output signal reaches or falls below a predefined further threshold value (S1).
