A method includes receiving an audio signal from a microphone and processing the audio signal to identify a signal component that is associated with a resonance of at least part of a microphone unit disposed on a vehicle. The microphone unit includes the microphone and a protective element arranged to shield the microphone from environmental material. The method includes determining, based at least in part on the identified signal components, a characteristic indicative of the protective element having shielded the microphone from environmental material.
