Abstract: Road noise masking for a vehicle includes determining, by a computer processor, an expected interior sound associated with the vehicle. The expected interior sound is defined by a design of the vehicle in conjunction with road conditions encountered by the vehicle. The road noise masking also includes monitoring, via the computer processor, information sources of the vehicle during a driving event. Upon determining a current road surface from the monitoring, the road noise masking includes calculating a masking noise shape commensurate with the expected interior sound, and transmitting instructions including the masking noise shape to an audio system in the vehicle. The audio system produces masking noise from a tuner of the audio system that approximates the masking noise shape.
