A system for controlling a sound level of a prime mover permitted to emanate from or within a vehicle includes a global positioning satellite (GPS) receiver operable for receiving a GPS signal and a sound control device. The sound control device is operable for increasing or decreasing a sound level of the prime mover in response to a control signal. A controller in communication with the GPS receiver includes a calendar and clock, and is programmed to execute a method, including receiving the GPS signal via the GPS receiver, and determining an actual location of the vehicle using the GPS signal. The controller also determines an actual date and time of day using the calendar and the clock, respectively, and transmits the control signal to the sound control device to increase or decrease the sound level using at least one of the actual location, date, and time of day.
