Abstract
An audio system of a vehicle includes a mode module that sets a mode signal to a first mode when a vehicle speed is greater than a predetermined speed and a longitudinal acceleration of the vehicle is less than a predetermined acceleration. The predetermined acceleration is less than zero and the predetermined speed is greater than zero. A sound control module, when the mode signal is in the first mode, selectively sets audio characteristics for a deceleration event of the vehicle based on randomization parameters. An audio driver module, based on the audio characteristics, applies power to speakers to output sound within a passenger cabin of the vehicle.
