According to foreign media reports, recently, DSP Concepts announced a cooperation with top audio company Bose. DSP Concepts is the developer of Audio Weaver, a sound effects platform that is used in Tesla vehicles. This collaboration will allow Bose to bring its QuietComfort Road Noise Control (RNC) technology to vehicles that support the Audio Weaver platform, such as the Tesla Model 3.
Over the years, the Tesla Model 3 audio system has won praise from reviewers for its high quality, and some even pointed out that it is one of the best in-car audio systems on the market today. According to reports, part of the reason is that Tesla hired former Bang & Olufsen (the world’s top audio-visual brand) engineers to purchase the best speakers and amplifiers on the market. Another reason is that its vehicles use the Audio Weaver platform, which provides A comprehensive audio development framework.
With the latest cooperation between DSP Concepts and Bose, Tesla and other automakers using the Audio Weaver platform can introduce Bose's QuietComfort RNC into their cars. QuietComfort RNC is a very clever solution. It combines accelerometers, signal processing software, microphones, and the car’s own audio system to electronically reduce target noises. These noises include vehicles running on uneven roads and grooves. The sound produced by concrete and uneven roads.
Last year, Bose launched the QuietComfort RNC solution. At that time, the company emphasized that how to minimize noise in the car during the rise of electric vehicles will be a key priority for car companies. Since electric vehicles have no engine noise, the noise generated by the road will be particularly noticeable. Bose's QuietComfort RNC technology is designed to suppress noise from outside the cabin.
All Tesla vehicles are electric vehicles. Because they use electric motors, they are very quiet when driving. However, both car owners and reviewers found that the road noise inside the vehicle is very obvious when driving at high speeds, especially the lower-priced Model 3. The Model 3 itself is a very quiet car, but the spring suspension it uses means that sometimes road noise can become very noticeable.
In the past few years, Tesla has adopted a number of optimization measures for Model 3 to improve the sound insulation effect of the cabin. The latest 2021 Model 3 uses double-glazed windows, which are currently off the assembly line at the Fremont factory and delivered successively. With Audio Weaver starting to support Bose's QuietComfort RNC, Tesla vehicles may become quieter when driving in the future.
