Abstract
A method and system for adaptive noise masking powertrain noise in a vehicle is described. The method comprises: determining frequency and amplitude characteristics of the powertrain noise; determining amplitude characteristics of background noise in the vehicle; dynamically generating a masking audio signal based on the determined characteristics of the powertrain noise and background noise; and outputting the masking audio signal in a cabin of the vehicle. The system includes: a processor; a memory storing processor-executable instructions that, when executed, cause the processor to determine frequency and amplitude characteristics of the powertrain noise and to determine amplitude characteristics of background noise in the vehicle; a masking noise generator for dynamically generating a masking audio signal based on the determined characteristics of the powertrain noise and background noise; and one or more vehicle cabin loudspeakers for receiving and outputting the masking audio signal in a cabin of the vehicle.
