System and method for producing an audible alert for a vehicle

A method for controlling a vehicle to emanate an audible alert, the method comprising:

• determining when the vehicle is operating;
• controlling a speaker system in the vehicle to emanate the audible alert outside of the vehicle for a period of time when the vehicle is operating based on stored information that is representative of an internal combustion engine noise profile, such that the audible alert has a sound profile that includes a simultaneous emanation of a first audible frequency component having a first frequency emanating at a first sound pressure level that is greater than a first representative sound pressure level of the internal combustion engine noise profile at the first frequency, a second audible frequency component having a second frequency emanating at a second sound pressure level that is greater than a second representative sound pressure level of the internal combustion engine noise profile at the second frequency, and a third audible frequency component having a third frequency emanating at a third sound pressure level that is less than a third representative sound pressure level of the internal combustion engine noise profile at the third frequency;
• and
• modulating the first sound pressure level of the first audible frequency component.
