Wheel Well Soundproofing

[TLLMRRJ]

And what about this liner for the frunk? Anyone try it?

Front Trunk Soundproof Cotton Mat Sound Proof Protector For Tesla Model 3 | eBay

If the wheel well liners of the same material help, then it makes sense that this would help too. Plus it gives a more finished/less plastic look to the frunk and won't scratch like the plastic.

I spent 5 hours today doing soundproofing. This was quite an effort but the results are fantastic for me. At 120 Km/h I reduced from 70-73 dB to 61-63 dB. A reduction of 10 dB is pretty massive and very noticeable. I realize this thread is for Wheel Wells so I will post a more extensive detailed update in the main thread on soundproofing, but here are some photos. For the moment I focused on the rear wheel wells, sub-trunk and trunk area, the parcel shelf (with the covering piece from Amazon) and the Frunk (with covering piece).

More photos here as we can only do 10 per post:

a combination of bitumen-backed and then closed-cell foam soundproofing materials will help a lot. Dynamat, Skinz and other makes available.

Cloud 9 floor underlay is also a superb material for soundproofing in cars.

The best approach will be one that has several layers with variety of materials to create some sort of sandwich effect.

Lots of great lessons from the car audio world for this problem - but watch out for pricing of the products as it gets a bit silly.

An all-weather boot liner will also help a lot, the trunk amplifies all road noise from the back as it is a resonator so you want to kill as much of that effect as possible alongside treating the rear areas as described by @webbah above.

Exactly. I have 3 layers in the most sensitive areas. One for low frequencies, one for insulation/dampening, and one for high frequencies.

I should point out that you also need to be conscious about the weight. Adding all of this added about 30 kilograms weight so far. However I have done other things to reduce weight in my car. One of the easiest was replacing the lead acid battery with an Ohmmu. And also lighter wheels.

Turn up your stereo!

Turn up your stereo!

Ahh yeah... But first was muting the road/tire noise and wind! Well worth it.

Just did some further testing with some local city driving. Absolutely incredible results. At 50 km/h I used to see 60 dB. I’m now seeing 48-50 dB. That is about the same as a quiet library for the record. I’m very pleased! A few other things I’ve done are setting my tires at 38 psi cold and installed door seals. I still hear some tire noise from the front so my next goal is to do the front wheel wells this weekend.

Note, I meant to say “quiet street” and not quiet library. I use dB Meter for iOS...

Any update? I just ordered the same and going to tackle wheel wells, doors, frunk and trunk.

I did the trunk floor with the noico and then was able to fit some of the thinsulate around the lower trunk area as well as noico, I thought that made a tiny difference...so I did the rear wheel wells with both not sure if there’s any difference to be honest. I think there’s less drone in the backseat area. Want to do more for giggles.

You have to be careful with placement of the thinsulate. It’s a bit thick. And yes I see the humor in that.

I also want to do some more work in the trunk. Just gotta find the time.

which area gave the biggest noise reduction? trunk? wheel wells? frunk?

 

[webbah]

Personally I think the rear wheel wells are best done from the inside. The fronts from the wheel wells on the outside by pulling the rims.

Very difficult to quantify. I haven’t done the frunk or front wheel wells yet so can’t comment on that. But I can now hear noise coming from the front more distinctly since the rear is a dampened now.

considering pulling the interior to get after it. But that’s a full day job and I just done have the time currently.

I took off the door panels and covered the doors with Noico; it definitely helped reduce noise and it was a pretty quick project.

You did all that in 5 hours? Impressive!

Thanks, but I’ve done it in all my cars over the years. It’s not too difficult if you have a garage and the right supplies on hand. Removing the panels and such is very easy as most of it is just held by clips.

How picky are you about tires now after all this insulation? I've been stressing about foam treated tires vs non treated and a lot of mixed answers online and from tire rack.

If Tesla want to stay ahead of the game they realy need to be doing this at the factory. I love my M3P BUT it's too noisy. At 70+ it becomes rather tiresome, especially on road surfaces that are less than smooth. It's the one aspect of the car that would potentially make me look at other car models if they become available.

So did anyone actually install the wheel well liners? Any feedback?
