Bose wants to bring its acclaimed noise-canceling technology from your
headphones to your car. The Framingham, Massachusetts-based company just
unveiled a new technology called QuietComfort which claims to measure your
vehicle’s vibrations in order to eliminate noise from your daily drive.
ELIMINATE NOISE FROM YOUR DAILY DRIVE
As noted by Bose, this type of noise-canceling technology is likely to gain
more prominence as vehicles get lighter and more electric. Sitting inside a
whisper-quiet electric car, a driver is exposed to more road noise than they
would typically hear in a noisy internal combustion engine car. Bose is
framing its technology as looking toward a future when there are many more
EVs on the road than there are today.
So how does it work? Conventional noise-canceling methods include thick
insulation or specialized tires to minimize noise from driving over rough
roads or uneven pavement. But these fixes can increase vehicle weight and
drive down fuel efficiency. This is not that.
Bose uses a combination of accelerometers, proprietary signal-processing
software, microphones, and the vehicle’s built-in audio system to “
electronically control unwanted sound.” According to the company:
Accelerometers mounted on the vehicle body enable a Bose algorithm to
continuously measure vibrations that create noise. This information is then
used to calculate an acoustic cancellation signal, which is delivered
through the vehicle’s speakers to reduce the targeted noise. Microphones
placed inside the cabin monitor residual noise levels, allowing the system
to adapt the control signal for optimized performance over different road
surfaces, while automatically adjusting over time as the vehicle ages.
It sounds incredibly high-tech, but we would need to test it out before
passing judgment. Bose has certainly made a name for itself in the world of
noise-canceling headphones, but a car is a much different, and more complex,
environment. The company notes that since 2010, its automotive division has
provided carmakers with EHC, a highly targeted technology for reducing
undesirable engine noise. Now it’s trying to do the same for the in-car
experience.
Bose says it will collaborate with automakers during the vehicle development
process to install its tech during production. The first QuietComfort-
enabled cars are planned to be in production models by the end of 2021. |
