Dynamat for whining / whistle / beeping inverter noise?

[agenthsu007]

Has anyone dried sound deadening / dynamatting their Tesla to eliminate the annoying sounds from their drive unit/inverter?

If so, did it work?

 

[agenthsu007]

No one?

NPR works pretty good for me.

You check some of the youtube videos on this. I kind of like a little noise when I press down hard on the accelerator.

Checked everything online. Went to two service centers with screenshots. They told me to F off. My car beeps like morse
Code, it doesn’t whine consistently.

What’s NPR?

 

[NewbyMaybe]

National Public Radio.

Do you have a golfcart type of noise?
How old is the drive unit?

2 months old. It’s a morse code like noise created by the drive unit whining.

Has an independent tech listened to it?

Not sure what you mean.

No one has used dynamat for their car??

 

[NewbyMaybe]

Not sure what you mean.

There are Tesla repair shops that are independent.

Is it like this sound? I have a 2018 model 3 dual motor with 64k miles. Bought it used from Tesla a month ago.

Yes

From my understanding, Dynamat helps with reducing vibration noises on large panels of sheet metal. If you choose to block noise, look into MLV (Mass Loaded Vinyl) sometimes backed with a CCF (Closed Cell Foam). I've done both to my Model 3 but didn't have an issue with motor noises to begin with.

Thanks. I’m thinking about dynamat for the panel under the car/below DU, all around the frunk, and MLV below the front rugs in the cabin. Think that might work?

I think it depends on your model year. I have a 2018 without the double-glazed door window glass, so most of my noise comes from the windows. That said, I wasn't trying to block the drive unit whine, I was working to block road noise. In my case, the biggest impact was changing the tires (I now use Vredestein Quatrac Pro 19"s) and adding some 3M Thinsulate between the roof shade and the glass to prevent sound from echoing off the interior glass.
