Abstract: A system for microphone noise reduction includes first and second filter portions and a control processor adapted to adapt the first and second filter portions in response to a one of a plurality of stored vectors. Each stored vector is representative of acoustic transfer functions in accordance with a model of a vehicle and a respective position within the vehicle. A method for processing microphone signals includes selecting a vehicle model, selecting positions within the vehicle model, measuring acoustic response vectors at the positions, storing the response vectors, selecting one of the response vectors, and adapting first and second filter portions in accordance with the selected response vector.
