Abstract
A method and system for noise suppression of a sound signal. The sound signal includes speech of a user while speaking. The system includes a first sound receiver that obtains a first sound signal and a second sound receiver that obtains a second sound signal. The first sound signal includes a first airborne noise signal when noise is present and a first airborne speech signal when the user is speaking. The second sound signal includes a second airborne noise signal when noise is present and a second airborne speech signal when the user is speaking. The first sound receiver is a vibration pickup or transducer that obtains an additional speech signal when the user is speaking. The additional speech signal is obtained in response to vibrations propagating through the user, the vibrations being caused by the user speaking, and the first sound signal includes the additional speech signal when the user is speaking. The system is adapted to suppress, during use, at least a part of the first airborne noise signal, when present, in the first sound signal.
