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 investors will be shocked by Jim Cramer’s latest assessment

Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.

When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.

Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.

He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.

Now, he is back to being a bull.

Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.

Jensen Huang’s Tesla Narrative

Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.

“It’s not a car company,” he said.

He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:

“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Robotaxi Launch

Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.

There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.

He said:

“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”

It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.

Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla already has nearly 12,000 Supercharger piles across mainland China. However, the company just initiated the rollout of the ultra-fast V4 Superchargers in China for the first time, bringing its quick-charging piles to the country for the first time since their launch last year.

The first batch of V4 Superchargers is now officially up and running in China, the company announced in a post on Chinese social media outlet Weibo today.

Tesla China teases arrival of V4 Superchargers in 2025

The company said in the post:

“The first batch of Tesla V4 Superchargers are online. Covering more service areas, high-speed charging is more convenient, and six-layer powerful protection such as rain and waterproof makes charging very safe. Simultaneously open to non-Tesla vehicles, and other brands of vehicles can also be charged. There are more than 70,000 Tesla Superchargers worldwide. The charging network layout covers 100% of the provincial capitals and municipalities in mainland China. More V4 Superchargers will be put into use across the country. Optimize the charging experience and improve energy replenishment efficiency. Tesla will accompany you to the mountains, rivers, lakes, and seas with pure electricity!”

The first V4 Superchargers Tesla installed in China are available in four cities across the country: Shanghai, Zhejiang, Gansu, and Chongqing.

Tesla has over 70,000 Superchargers worldwide. It is the most expansive and robust EV charging network in the world. It’s the main reason why so many companies have chosen to adopt Tesla’s charging connector in North America and Europe.

In China, some EVs can use Tesla Superchargers as well.

The V4 Supercharger is capable of charging vehicles at speeds of up to 325kW for vehicles in North America. This equates to over 1,000 miles per hour of charging.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi

Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.

Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.

A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.

The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.

The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.

With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.

CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”

Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.

Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.

Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.

For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.
