Tesla audio partner DSP Concepts discusses noise cancellation tech & the future of sound in autonomous cars
Sound might play a bigger role in the auto industry with the advent of the electric cars and the age of autonomous vehicles dawning. Tesla’s audio partner DSP Concepts (DSPC) knows a lot about sound and how big of a role it plays in everyday life. Teslarati spoke with part of the DSP Concepts team, who revealed the significance of sound in vehicles, especially as the electric car revolution starts to hit its stride.
“It turns out a car is your most complicated audio product,” said Chin Beckmann, the co-founder and CEO of DSP Concepts. Beckmann described all the ways audio and sound play a part in how people interact with their vehicles, like phone calls, voice commands, or simple in-car communication from driver to passenger and vice versa.
Engine noise cancellation is a feature that interests traditional cars owners as well. Inversely, for electric car owners, engine noise enhancements or noisemakers have become a sought after feature, particularly in the United States where it is mandatory for EVs.
Tesla probably contributed to the popularity of noisemakers in vehicles with its recently-released Boombox feature, which allows drivers to play sounds through an external speaker. Funnily enough, EV owners seeking to increase the noise coming out of their vehicles, may also be looking for ways to decrease the sounds coming into their cars.
“There’s a lot of interest in road noise cancellation from EVs,” said Dr. Paul Beckmann, founder and CTO of DSP Concepts.
Last month, DSP Concepts announced that Audio Weaver would port Bose’s QuietComfort Road Noise Control (RNC) technology into its platform. The collaboration meant that car companies using the Audio Weaver platform, like Tesla, Porsche, or BMW, could offer Bose’s QuietComfort RNC to their vehicles.
Dr. Beckmann clarified, however, that some hardware needs to be integrated into the vehicle for the Bose QuietComfort RNC to work.
“The way the RNC works is it uses microphones inside the car to listen. It’s kind of like those active noise cancelling headphones. The headphones have microphones close by your ears. So [for] the retrofit, you’d have to put microphones, maybe, by the headrest or somewhere close to your ears,” he shared with Teslarati.
Dru Wynings, Sr. Director of Marketing at DSP Concepts, added that some sensors would probably be needed in the car’s chassis as well. He also talked about the complexities of bringing Bose’s QuietComfort RNC to vehicles.
“There’s a huge hardware component to it in terms of how much computation is needed, in terms of what their audio sound system is…all of that could take a toll. So, [automakers are] planning on what could actually fit on this specific chip to run this software,” said Wynings.
DSP Concepts did not reveal any details about Bose RNC coming to Tesla vehicles. There’s really no telling what features Tesla will roll out to its vehicles at the end of the day.
However, the possibility is very high. It isn’t too far-fetched to think that Tesla might have already equipped its vehicles with the necessary hardware for features like Bose’s QuietComfort RNC, especially considering the upcoming release of the much-anticipated Model S and Model X refresh. The company already did something similar with its in-cabin camera. The hardware for the camera feature was equipped well before it was enabled via an OTA software update.
Road noise cancellation seems like a premium feature that could be available for Tesla’s top-tier vehicles, like the Model S and Model X. Or Tesla may roll out the Bose RNC feature to its entire fleet in a later update. After all, the Model 3 just had a refresh as well.
Sound in Autonomous Vehicles
Aside from Tesla, DSP Concepts works with an array of automakers in the industry, both old and new companies. The company’s main goal is to bring audio engineering into the 21st century with the help of Audio Weaver.
When it comes to the auto industry, DSPC seems very aware of how audio in cars will evolve as autonomy enters the industry. It has become evident that car companies, both legacy and startups, have started producing more tech-savvy vehicles.
Tesla vehicles might be the most tech-savvy cars on the market. The EV manufacturer’s cars incorporate technology that people might look for in their vehicles now, like Netflix, Spotify, or even Caraoke. Yes, these features might not be necessary, but the same argument could be made for phones, laptops, or other devices.
People can do much more than call others with their phones now. They can watch their favorite shows, listen to music, search the internet and much, much more. People seem to want their tech to be well-rounded, so why not their vehicles?
Other car makers seem to be following Tesla’s footsteps. In addition to making more tech-oriented vehicles, more auto companies are also exploring autonomous cars.
With autonomy in the picture, features like Tesla Theater or Tesla Arcade will be more utilized and with that comes the significance of sound. DSP Concepts understands that people might start looking for better sound quality in their autonomous vehicles as more entertainment options are offered by car companies.

Tesla Q3 2025 earnings: What analysts expect
The automaker delivered a record 497,099 vehicles and logged its highest-ever energy storage sales in Q3 2025.
Tesla’s (NASDAQ:TSLA) Q3 2025 earnings, which would be released after markets close today, could prove to be a test of confidence for the company’s shareholders.
The automaker delivered a record 497,099 vehicles and logged its highest-ever energy storage sales, but analysts noted that these gains might have come at a cost.
Record vehicle deliveries
Tesla’s profit per share is expected to fall about 25% year over year to around $0.53–$0.55, even as revenue rises from 4% to 6%, as noted in a report from Market Pulse. Analysts noted that Tesla’s record quarter was partly fueled by buyers rushing to complete purchases before the U.S. federal EV tax credit expired in September, a surge that could dampen Q4 demand. The company also dipped into its inventory to reach the record delivery number.
Analysts expect automotive gross margin (excluding regulatory credits) to land between a conservative 16.5% and 17%. This suggests that a good portion of Tesla’s Q3 delivery growth came from aggressive price cuts. If margins fall below 16.5%, it could hint at more cost pressures that the company would have to handle in the coming months.
Tesla’s Energy segment, meanwhile, is expected to act as a stabilizer. The business deployed 12.5 GWh of storage in Q3, driven by strong demand from AI data centers. Analysts expect this high-margin division to partially cushion the hit from the automaker’s thinner car profits.
AI, FSD, and Musk’s role
Tesla’s lofty valuation, trading about 17% above the average analyst consensus of $365, would likely depend heavily on investor belief in its AI and robotics initiatives. Industry watchers have stated that management must deliver credible updates on Full Self-Driving and the Robotaxi program to help justify the company’s current valuation.
Elon Musk’s proposed 2025 CEO Performance Award, which proxy advisors have urged shareholders to reject, would likely be discussed in the Q3 2025 earnings call has well. Musk has hinted that a failed vote could jeopardize Tesla’s AI strategy, making the company’s upcoming results quite crucial for market confidence.

Tesla Board Chair defends Elon Musk’s pay plan, slams proxy advisors
The letter comes ahead of Tesla’s 2025 Annual Meeting, where shareholders will vote on several key proposals.
Tesla Chair Robyn Denholm has issued a strongly worded letter urging investors to reject the latest recommendations from proxy advisory firms ISS and Glass Lewis, saying their “one-size-fits-all” approach fails to recognize Tesla’s unique business model and track record.
The letter comes ahead of Tesla’s 2025 Annual Meeting, where shareholders will vote on several key proposals including Elon Musk’s 2025 CEO Performance Award and director reelections.
Tesla slams proxy advisors’ models
Denholm criticized both firms for consistently opposing Tesla’s growth-oriented plans, noting that the company’s market capitalization has increased twentyfold since shareholders approved Musk’s 2018 performance package, which both advisors had opposed at the time.
“Our shareholders have ignored their recommendations, and it’s a good thing they did,” she wrote. “Otherwise, you may have missed out on our market capitalization soaring 20x while the proxy advisors time and time again recommended “against” Tesla proposals designed to promote the sort of extraordinary growth we have enjoyed.”
The letter argued that Glass Lewis and ISS use robotic policies that don’t account for Tesla’s innovation-driven structure. Tesla’s leadership maintained that the 2025 CEO Performance Award will only reward Musk if he achieves extraordinary market capitalization and operational goals. The plan, Denholm stated, aligns Musk’s incentives with long-term shareholder interests.
Tesla defends board leadership
Denholm also defended directors Ira Ehrenpreis and Kathleen Wilson-Thompson, calling them pivotal to Tesla’s governance and innovation strategy. She said both have driven Tesla’s growth and helped design compensation systems vital to competing in the AI and robotics talent race.
She warned that following ISS and Glass Lewis could turn Tesla into “just another car company,” and urged shareholders to “vote yes to robots, and reject robotic voting.” The letter also highlighted that neither ISS nor Glass Lewis owns Tesla stock, emphasizing that only shareholders “who have made an actual financial investment” should decide the company’s direction.
“If you prefer that Tesla turn into just another car company mired in the ways of the past, then you should follow ISS and Glass Lewis. If you believe that Tesla, under the visionary leadership of Elon and the oversight of a Board that includes business leaders with integrity like Ira, Kathleen and Joe, then you should vote with Tesla,” Denholm wrote.

Tesla Model S and Model X make a comeback in Europe
The updates inside and under the surface of the new Model S and Model X are meaningful.
Tesla’s luxury flagships are making a comeback in Europe. After disappearing from Tesla’s online configurator in July, the Model S and Model X are once again available to order across the region.
Deliveries are set to begin in November, with the Model S priced from €109,990 and the Model X starting at €114,990. The update brings improved comfort, reduced cabin noise, and efficiency improvements to the two veteran EVs.
A subtle refresh
Tesla’s design team made only light exterior changes, but the updates inside and under the surface of the new Model S and Model X are meaningful. The refreshed Model S and Model X now feature upgraded insulation, enhanced active noise cancellation, and retuned air suspension to make the ride smoother and quieter.
New 19- or 21-inch wheels and ambient interior lighting add a subtle modern touch to the two flagships, while the Model X’s third-row seating has been improved with more space for occupants, Tesla Europe and Middle East noted in a post on X.
Both vehicles gained adaptive headlights, blind-spot warning lights, and a standard front camera. Efficiency has also improved thanks to new aerodynamic rims and low-rolling-resistance tires. The Model S now boasts a WLTP range of 744 kilometers, while the heavier Model X can travel up to 600 kilometers on a single charge.
Tesla’s performance flagship
The Model S Plaid, Tesla’s performance flagship, benefits from deeper upgrades in this cycle. The vehicle now features a redesigned front fascia and a new front splitter. Its rear aprons have also been updated, and it has been given a carbon rear spoiler and diffuser to enhance high-speed stability.
Underneath, the drive rotors receive carbon sleeves for better performance under extreme loads. The Plaid sprints from zero to 100 kph in just 2.1 seconds and can reach 322 kph with optional ceramic brakes, while maintaining an impressive 611-kilometer range. Considering its performance figures, the Model S Plaid has once again become the market’s best bang-for-the-buck flagship performance car.
