I want to reduce road noise in my 2016 RAV hybrid but could not find any company so I'm attempting it myself.

Most is self explanatory, I will post some pictures.

Bought alot of dampening material.

Silent Coating Vibro Damping 2mm
Silent Coating Sound Absorber 6mm
Silent Coating Noise Isolator 7mm

Cost about $400 but plenty of it

Starting with doors (close to zero dampening material it appears)



Window down for measuring clearance

I look forward to your progress. As some know, I had my entire floor, rear hatch, rear quarters, and all doors sound deadened on my 2016 SE by a local shop. They used the Ballistic sound deadener.

Road noise was only reduced about 2-3 decibels (helped some), but the biggest difference I notice are stereo sounds better and cleaner, doors now sound and close like a Lexus, and tapping on all door panels and quarter panels is a complete change to a quality sounding and feeling built car. Also, this helps with small door ding resistance, and insulates the car better to retain heat / cool air.

You are adding additional material than I had done, so your results may well be even better.

Best of luck....keep us updated.

Thanks KJPAT08! I'm gonna add alot. It's quite fun but labor intensive.

Thanks for your previous advice over PM also.

First real test, front doors only. Lost 3-4 db at 55mph. Car is now VASTLY improved in road noise i took it up to 75mph there is just wind noise now.

The road noise left comes from behind now, I think from the trunk area.

Really really happy sofar this was the only problem with this orherwise perfect car!

Here are a couple of pics of the interior on my 2016 before and after. There was a fair amount of factory soundproofing as you can see.

Great pictures!

Those grey patches that come stock are the same ones I noticed in the trunk. When I added dynamat ½ year ago in the trunk there was almost no gain. I suspect it's better to use a noise absorber mat in those places where Toyota already have put some dampening in from the beginning.

Did the other side really labor intensive more irregular shapes.

Added 3 spare isolator sheets above spare just for fun/placebo

I found out it is easy to add some extra absorber by sliding it carefully under the "main" carpet.

Let see if it helps otherwise I can undo it, didnt remove the sticky side.

OK the fix above is a very big improvement on very bad tarmac. The difficulty is about 1/10 for the floor fix, 6/10 for a door and 8/10 for the trunk wheel wells

How much in your currency, and I will convert to US dollars? Estimated total time? And good job, by the way.
