The all-electric mic also includes a 14-speaker Bose surround sound audio system

FRAMINGHAM, Mass., March 21, 2022 /CNW/ – With the launch of the 2022 GMC HUMMER EV pickup, Bose is showcasing its first-ever application of Electric Vehicle Sound Enhancement (EVSE) technology, bringing unprecedented sound experiences to consumers of the first all-electric supertruck in the world. Bose EVSE technology, along with a 14-speaker Bose surround sound system, is standard on the all-new GMC HUMMER EV.

EVSE technology helps GMC deliver dynamic audio response to the HUMMER EV driver and passengers. Designed to replace the mostly quiet cabin that accompanies electric vehicle driving, EVSE technology sends personalized propulsion sounds into the cabin through Bose speakers to refine and enhance the acoustic environment. Combined with the immersive music provided by the Bose audio system, the interior of the GMC HUMMER EV is unlike anything else on the road today.

“The GMC HUMMER EV delivers sensory excitement along with incredible on-road and off-road performance,” said Al Oppenheiser, Chief Engineer, GMC HUMMER EV. “The sense of sound is an important element, and we turned to our longtime partners at Bose to help us balance the appropriate level of acoustic precision with driver input, without compromising the enjoyment of an EV experience. almost silent.”

“The launch of our all-new audio solution in an awesome vehicle like the GMC HUMMER EV is both exciting and rewarding,” said Pierre Kosack, vice president of Bose Corporation and head of the Bose Automotive Systems division. “Getting behind the wheel of this supertruck is simply breathtaking and we can’t wait for consumers to feel and hear what it is.”

First use of Bose EVSE technology

During the vehicle development process, Bose engineers worked closely with GMC to incorporate EV sound-enhancing technology. Using a proprietary Bose algorithm and data gathered from the vehicle, EVSE helps mask unwanted noise produced by the electric drive system, while generating distinct sounds for different driving modes:

  • In normal driving, the sound is subtle, providing an audio textural layer to the vehicle’s on-road performance.
  • Switching to Terrain mode introduces a heavier bass tone to help the driver stay connected to the performance of the vehicle. As the torque of the GMC HUMMER EV increases, the sound gradually increases, keeping the driver in tune with the power and movement of the vehicle over various types of unpaved terrain.
  • In off-road mode, a deeper rumble is heard when the vehicle is moving quickly over rough surfaces, such as dirt, gravel and sand.

The sound of ‘Watts to Freedom’

The impact of EVSE technology is most pronounced in the GMC HUMMER EV’s driver-selectable launch control mode, called “Watts to Freedom,” which lets the driver and passengers feel the full power of acceleration of the supertruck from 0 to 60 MPH in a GM-estimated 3 seconds.

As the vehicle prepares for launch from a standstill, EVSE technology is engaged to help prepare occupants with audio cues. A deliberately crafted mix of electric guitar riffs and feedback gradually builds anticipation as the Bose subwoofer creates vibrations and the vehicle uses its adaptive air suspension to lower its height and center of gravity. The sound then changes, signaling that the vehicle is ready to take off before the driver can finally unleash the HUMMER EV’s 1,000 horsepower and 11,500 lb-ft. couple on the road.

The Bose surround sound system for GMC HUMMER EV

For music and audio entertainment inside the GMC HUMMER EV, Bose applies its 40 years of experience in the automotive industry to design a 14-speaker audio system that delivers deeply impactful listening.

The Bose surround sound system delivers intense low-frequency performance, powered by 6 x 9-inch wide-range woofers – one in each front door – and an all-new subwoofer design, positioned under the rear seat and visible to passengers with a Bose logo for an experience that can be seen, heard and felt like never before.

The system also includes proprietary Bose Centerpoint digital signal processing for immersive surround sound in every seat and Bose AudioPilot signal processing to preserve the listening experience in all driving conditions, even when the removable roof panels of the HUMMER EV are turned off.
