A method of reducing wind noise in a microphone signal received from a microphone, the method comprising:
- receiving one or more accelerometer signals from one or more accelerometers in proximity to the microphone;
- determining a subband power in one or more of the one or more accelerometer signals;
- estimating a cut-off frequency of noise in the microphone signal based on the determined subband power;
- and
- reducing wind noise in the microphone signal using the estimated cut-off frequency.
