FRAMINGHAM — With the launch of the 2022 GMC HUMMER EV Pickup, Bose is introducing its first application of Electric Vehicle Sound Enhancement (EVSE) technology, sound technology to an EV truck. Bose EVSE technology, along with a 14-speaker Bose surround sound system, is standard on the new GMC HUMMER EV.
EVSE technology helps GMC deliver an audio response for HUMMER EV’s driver and passengers. Engineered to replace the mostly silent interior that comes with operating an electric vehicle, EVSE technology sends propulsion sounds into the cabin through Bose speakers to refine and enhance the acoustic environment.
“The GMC HUMMER EV offers sensory excitement along with incredible on- and off-road performance,” said Al Oppenheiser, chief engineer, GMC HUMMER EV. “The sense of sound is an important element, and we looked to our longtime partners at Bose for expertise in helping us balance the appropriate level of acoustic precision with driver input, yet not compromising the enjoyment of a near-silent EV experience.”
During the vehicle development process, Bose engineers worked closely with GMC to integrate Electric Vehicle Sound Enhancement technology. Using a proprietary Bose algorithm and data gathered from the vehicle, EVSE helps mask undesirable noise produced by the electric propulsion system.
The system also includes proprietary Bose Centerpoint digital signal processing for enveloping surround sound in every seat and Bose AudioPilot signal processing to preserve the listening experience in all driving conditions — even when the HUMMER EV’s removable roof panels are off.
