Zusammenfassung:The method comprises receiving a first microphone signal from a first microphone having a first frequency response characteristic at frequencies associated with wind noise and receiving a second microphone signal from a second microphone having asecond frequency response characteristic at frequencies associated with wind noise. The first frequency response characteristic 1101 provides less gain than the second frequency response characteristic 1102 over the range of frequencies associated with wind noise 114. The first and second microphone signals are then processed (fig 3) to detect the presence of wind noise.
