Abstract
A voice pick-up arrangement () provides improved voice performance in a wireless headset () exposed to loud environmental noise. A air microphone () and a vibration sensor () are used for sound pickup. An adaptive filter () may be used to subtract the noise from the vibration sensor output in a subtractor (), thus producing a clear voice signal. A noise level may be monitored and be used for determining whether the adaptive filter is used or for determining the coefficients of the adaptive filter (). A beam-forming array may be used to suppress a voice component of the picked-up air microphone audio signal.
