Gaming headset with active noise cancellation
A gaming headset system for use in a game event. A headset (HS) has a mouth microphone (MM), and a headphone with over-the-car car-cups (EC) each having inside a loudspeaker transducer (LT) and a feed-back microphone (FB). A feed-forward microphone (FF) is placed on an exterior part of the car-cups (EC). An ambient noise and speech suppression system (ANSS) serves to attenuate ambient noise and suppress intelligibility of ambient speech sound reaching the gamer (GM) in response to input signals indicative of sound captured by one or more of: 1) the mouth microphone (MM). 2) the feed-forward microphones (FF), 3) the feed-back microphones (FB), and 4) one or more sources (GSP_I. AUDM) located external to the car-cups (EC). The ambient noise and speech suppression algorithm comprises an active noise cancellation algorithm part (ANC) and a masking noise signal algorithm part (MSK) which in combination provides an effective active attenuation of noise and speech reaching the gamer and ensuring that even weak speech sounds will not be understood by the gamer. E.g. the ANSS algorithm may use microphones near the game speaker or game commentator and/or the audience for the ANC algorithm part and/or the masking noise signal algorithm part.
