Abstract: Examples of the disclosure relate to an apparatus (201) for determining whether one or more microphones (207) within a plurality of microphones is blocked. In examples of the disclosure correlation between at least two microphones is estimated so as to provide an indication of whether or not incoherent noise, such as wind noise (205), is present. This can be used to avoid incorrectly identifying a microphone as being blocked and so can help to maintain a higher quality level for the audio signals captured by the microphones.
