DSP Concepts, which supplies its Audio Weaver technology to Tesla vehicles, has signed an agreement with Bose. This collaboration could make it possible to equip the next models of the Californian giant with a noise reduction system signed by Bose: the QuietComfort Road Noise Control.
Improve the sound insulation of the passenger compartment of electric vehicles. Tesla has been working on it for years, with notable success, but its next vehicles could take a new step in this area.
As reported by the specialized site Teslarati, DSP Concepts (which develops the Audio Weaver software used by Tesla) recently announced that it will now collaborate with the American audio equipment manufacturer Bose. This agreement could become really interesting for Tesla since Bose has a very promising technology for the automotive world: the QuietComfort Road Noise Control system (aka RNC).
As the name suggests, this is an active noise reduction solution. Similar to that present in the manufacturer’s headphones, it is designed to reduce, this time in a passenger compartment, the noise generated by the road as well as the different surfaces and terrains on which the vehicle will be driven.
Sensors everywhere to analyze road noise
To reduce noise in the cabin, the Bose RNC system uses all the tools at its disposal: the vehicle’s accelerometers, its signal processing software, its microphones, but also its audio system. Finally, Bose uses detectors placed at the level of the vehicle’s suspension to allow its technology to understand what type of road is being taken (rough roads, grooved concrete, paved road, uneven pavement, etc.) and thus compensate for the noise emitted by the road. interior of the cockpit.
As Bose explains in the video above, this technology is intended primarily for electric vehicles since they cannot rely on the noise of their engine to mask the hustle and bustle of the road. The idea is therefore to make the driving experience even quieter inside vehicles that are already pleasant from this point of view.
We can also imagine that if the next Tesla models do have QuietComfort RNC technology, their audio quality will be even better. In this regard, the manufacturer can already count on speakers and amplifiers designed by former engineers from Bang & Olufsen, but also on the Audio Weaver software from DSP Concepts, which is best used to calibrate this equipment.
