Abstract: The invention discloses a method and system for providing an acoustic sound design for an electrified vehicle Acoustic Vehicle Alerting System (AVAS). The method minimizes annoyance from sound leaking into a vehicle compartment. Road and other functional vehicle made sounds (tread noise, fans, wind noise etc.) are used to create an alert sound that mimics these existing vehicle sounds and can be potentially masked, interiorly, by those same sounds. The sounds are recorded and thereafter shaped, amplified and broadcast by speaker(s) placed outside the interior cabin, i.e., one in an engine compartment and another at a rear of the vehicle, so that vulnerable road users can hear the approaching hybrid/electric vehicle. The sound meets jurisdictional requirements in accord with specified frequencies and sound levels. The result is an alert sound perceived as non-irritating and pleasant outside the vehicle, and unobtrusive and background inside the vehicle.
