Signal processing device according to any of the previous claims further comprising an absolute value extracting device (180) for estimating the absolute value of said first beamformed signal and wherein the power estimator (10) analyzes the result of said absolute value extraction in order to produce in frequency bands said first statistical estimate of the energy of said first part of an incident sound field.

Method for processing signals from at least two microphones (121,122) in dependence on a first sound field comprising processing the microphone signals to provide at least two beamformed signals (V1,1, V2,1);

• processing the microphone signals (mic1,mic2) together with the beamformed signals (V1,1, V2,1) in order to generate in frequency bands at least two statistical estimates of the energy of sources of wind noise in said first sound field;
• processing said generated statistical estimates in order to generate in frequency bands a first gain signal in dependence of said statistical estimates;
• processing an input signal (mic1,mic2,rx) to the signal processing device in dependence of said generated first gain signal.
