Abstract: A system is provided that includes an audio source configured to drive at least one audio output and a module under calibration integrated in a vehicle. The module under calibration is configured to receive a calibration command sequence from the audio source and decode the calibration command sequence into a digitally-encoded calibration command. The module under calibration is further configured to select a set of calibration data from a plurality of sets of calibration data to configure the module under calibration based on the digitally-encoded calibration command.

Abstract: A method of masking sounds associated with a vehicle is provided. The method includes performing on processing circuitry, monitoring of vehicle data. A tonal disturbance type and a tone to mask associated with the tonal disturbance type are identified based on the vehicle data. A shaped band of sounds is determined based on the tone to mask. The shaped band of sounds covers a range of frequencies around the tone to mask. The shaped band of sounds is applied to an audio output of the vehicle.
