Different parameters are supplied to a noise reduction algorithm based on the detection of different vehicle conditions, thereby allowing the noise reduction algorithm to process audio input differently depending on the corresponding vehicle conditions, such as speed, motor rpm, radio on/off status, window open/closed status, occupancy and position of vehicle seat(s), or any combination thereof. One or more vehicle conditions are detected by the vehicle and communicated to a noise reduction control device that determines the appropriate noise reduction algorithm parameters to use based on the detected vehicle conditions, advantageously with reference to a plurality of stored sets of noise reduction algorithm parameters previously established through a calibration process and stored in memory. Received audio input from a microphone array associated with the vehicle may be processed by the noise reduction algorithm as adapted by the appropriate parameters and used by a mobile terminal or the vehicle as appropriate.
