Bose Noise-Cancelling Technology: Coming Soon to a Car Near You
Many professionals in the auto and tech industries claim that as vehicles get lighter and more electric, road noise will increase. Bose is one of the companies set to combat this future dilemma by applying noise-cancelling technology to car interiors.
At CES 2019, Bose announced revealed its unique QuietComfort Road Noise Control (RNC) to electronically mute road noise in vehicles. This system uses accelerometers, microphones, the vehicle’s built-in audio system, and proprietary signal-processing software.
As illustrated by the following video, accelerometers measure the movements and vibrations that create the road noise. Via the sound system, the RNC technology projects an acoustic cancellation signal to help reduce the cabin noise.

John Feng, manager, Bose Automotive, Active Sound Management Solutions, expressed pride in the company’s latest achievement. “It’s much more difficult to control noise in a large space like a car cabin compared to the relatively small area around your ears,” he said. “[Bose has] achieved a level of road noise reduction that sets [it] apart [from rivals].”
It’s a natural move for the company, considering that it’s provided automakers with Engine Harmonic Cancellation (EHC) — a highly targeted technology for helping minimize engine noise — since 2010. Now, it is expanding its solutions to address in-cabin noise for vehicles.
Per The Verge, Bose plans to implement the QuietComfort RNC system on production models sometime in 2021.
