Interior Noise Reduction For Tesla Model 3
Interior Noise Reduction For Tesla Model 3
Interior Noise reduction for tesla model 3. Tesla increases the noise of the Model 3 interior cabin in the latest production car. Tesla CEO Elon Musk recently answered questions about Tesla interior cabin noise in the Model 3, noting that the problem has “significantly increased in current production”.
EV drives do not like noise. The sound of the wind is the wind that howls at you. And tire/road noise is also annoying.
Cabin noise is a common problem with Tesla Model 3 owners at the beginning of production, prompting some third-party vendors to offer products designed to make the drive quieter, such as door locks. Tesla has designed acoustic tires, which are specifically focused on reducing interior cabin noise.
Electric vehicles, unlike traditional combustion engine cars, do not have engines, transmissions, and exhaust sounds that help drown out normal noise on the road. But in tests performed on twenty different levels of electric vehicle cabin noise by Bjørn Nyland, three different variants of the Model 3 were performed at 50% lower, citing average noise between 68 and 69 decibels. The quietest vehicle tested was the Audi e-Tron, with a level score of 62.9 dB.
The noise source is reduced to wind noise that spreads through improper seals and weather debris on vehicle doors, as well as other uninsulated areas that increase wind noise. The faster a person moves, the more wind sounds.
While Musk did not elaborate on the extent to which Tesla made special changes to reduce cabin noise, we do know that this problem has been addressed by the company and will likely be improved with the new Model 3.
In the past, Musk has teased the idea of a sound system that adjusts the volume according to the cabin noise, however, this technique will not completely solve the problem, and will eventually add more noise. Tesla will solve the problem from its source by trying to eliminate it instead of covering it with another voice.
Tesla and Musk are notorious for listening to consumers and fulfilling requests they make to upgrade their vehicles. Joe Mode is one example when parents state that he had a problem with the Tesla Autopilot jump that developed their child.
Musk encountered this problem and released Joe Mode with the V10 update. Cabin noise is a problem Tesla has faced in the past, but the company is working diligently and seems to have found a way out of this problem in the production phase.
How are wind and road sounds produced? I will explain both and then provide a solution to reduce noise. The goal is to make the Model 3 driving experience more enjoyable than ever.
1. Wind Sound
The sound of the wind is caused by the wind that hits the surface of the car and enters the gap of the panel. This causes turbulent airflow. The more turbulent the air, the noisier.
One of the main sources of wind noise is the gap in the panoramic roof. This noise reduction kit fills the gap with a rubber gasket. This allows air to flow smoothly through the gap, reducing wind noise.
Reduction of wind noise can be seen, especially since the panoramic sunroof is right next to your head/ears.
It was cheap, only needed 10 minutes to install, and from my test in my car, it worked very well.
Similarly, the gaps on the door panels cause a lot of wind noise because there are a lot of panel gaps (basically 3 gaps per door). This door cover kit reduces the wind noise caused by gaps due to rubber weather release.
Like noise reduction tools, door coverings are also inexpensive. And it can be installed in about 30 minutes.
From experiments, this door cover can reduce noise by 2 to 4 dB at highway speed.
As an added benefit, this seal also keeps the door frame clean (dirt/mud kicked by the front wheels cannot enter the door panel gap).
2. Road Noise
Another source of noise is road noise. Road noise is the sound that comes from sidewalks, tires, electric motors, brakes, etc. The most noticeable is the sound of pavement and tires.
Lots of noise entering the trunk space as it does not have much acoustic insulation. The top of the stem is made of hollow metal and the sound passes through it. So his voice flowed from outside the car, into the trunk easily, and from there he easily entered the cabin.
This layer of cotton solves this problem by covering all common metals and providing sound insulation for luggage. It is installed in just 10 minutes.
This front-facing (“frunk”) cotton liner also covers bare metal and provides sound insulation for the front trunk. It is also installed in just 10 minutes.
An added benefit is thermal insulation, which is also available for items you place in your front luggage.
