Abstract: An audio control system of a vehicle includes a sound control module configured to determine N magnitudes for outputting a predetermined sound at N predetermined harmonics of a base frequency, respectively. N is an integer greater than one. An adjustment module is configured to determine N magnitude adjustments for the N predetermined harmonics, respectively, based on a helmet worn by a driver of the vehicle. The sound control module is further configured to determine N adjusted magnitudes for the N predetermined harmonics based on: the N magnitudes for the N predetermined harmonics, respectively; and the N magnitude adjustments for the N predetermined harmonics, respectively. An audio driver module is configured to, based on the N adjusted magnitudes, apply power to at least one speaker of the vehicle and output the predetermined sound at the N predetermined harmonics of the base frequency, respectively.

Abstract: A sound control module is configured to, based on a type of road over which a vehicle is traveling and a smoothness of the road, at least one of: determine a first frequency and a first increase at which to increase a first magnitude of a microphone signal; and determine a second frequency and a first decrease at which to decrease a second magnitude of the microphone signal. An audio driver module is configured to: receive the microphone signal from a microphone of the vehicle; generate an adjusted microphone signal by at least one of: increasing the first magnitude of the microphone signal at the first frequency based on the first increase; and decreasing the second magnitude of the microphone signal at the second frequency based on the first decrease; and apply power to a speaker of the vehicle based on the adjusted microphone signal.

Abstract: A system according to the present disclosure includes a launch identification module and a speaker control module. The launch identification module is configured to monitor a speed of a vehicle and identify a vehicle launch when the vehicle speed increases from zero to a value greater than zero. The speaker control module is configured to monitor an acceleration of the vehicle control a speaker in a cabin of the vehicle to play a first sound that simulates a sound produced by at least one of an engine and a driveline during a vehicle launch when a vehicle launch is identified and the vehicle acceleration is greater than a predetermined acceleration. The speaker control module is also configured to control the speaker to not play the first sound during a vehicle launch when a vehicle launch is identified and the vehicle acceleration is less than or equal to the predetermined acceleration.
