Bose QuietComfort Tech Aims To Minimize Road Noise In The Cabin

Bose has just premiered its QuietComfort Road Noise Control technology and will offer the innovative system to global vehicle manufacturers.

Those who keep track of the headphone world will know that Bose’s QuietComfort noise cancellation technology is perhaps the very best in the business. The company has used its headphone expertise to develop a version of the technology for use in automotive applications in a bid to avoid unwanted sound in the cabins of vehicles.

Traditionally, car manufacturers would need to add thick sound insulation, special tires, and other measures to minimize road noise. This adds weight and hurts fuel efficiency. Thankfully, Bose believes its system is a much better solution.

Bose QuiteComfort Road Noise Control technology uses accelerators, microphones, proprietary signal-processing software, and the vehicle’s audio system to control unwanted sound. The accelerators placed on a vehicle’s body trigger a Bose algorithm that detects noise-creating vibrations. The information gathered is then calculated to create a specific acoustic cancellation signal that’s delivered through the vehicle’s speakers to minimize noise. Microphones are then used to monitor residual noise, allowing the system to quickly adjust its levels as road noise changes.

The company already offers its Engine Harmonic Cancellation and Engine Harmonic Enhancement systems to reduce and alter the sounds generated by vehicle engines. Nevertheless, Bose expects its more advanced QuiteComfort RNC system to debut in road-going production models by the end of 2021.

    This is probably a good development. Surround sound can also be used for directional feedback, so you can “hear” vehicles in your dead spots, and give support when parking etc.

    They have been claiming this crap works for year and yet I have never entered any vehicle as quiet as those with good old fashioned (and heavy) double glazed glass, tons of sound insulation matting, extra door seals, etc. I do hope this latest generation of this tech does work, but given how much noise comes through vibrations, loosely secured or unpadded clips and other items, I don’t think anything will overcome shoddy NVH engineering.
