Second Skin Luxury Liner Pro - 2 in 1 Sound Insulation for Cars - Mass Loaded Vinyl and Closed Cell Foam - MLV Noise Barrier Made in USA (1 Sheet)

I have a 2021 Chevy Tahoe. Normal decibel level was 70-73 db without any sound dampening. I drive a lot and on louder roads so this was hurting my ears and causing me fatigue. I Put this under front floor mats, laid it on floor board in 2nd and 3rd row and then 3 strips across the back cargo area when 3rd row seats are down.This is perfect for dampening sound on floors and trunk.In addition to this I insulated doors with a stick on lighter closed cell foam product.It lowered overall decibel levels to 64-67 on the same roads.Major difference in ride quality.

This stuff works awesome! So far I've only added the luxury liner pro on the whole driver side floor over dynamat extreme. I also put under drive seat, I took the seat out and lined all down the seat bracket on front side and back side then cut a slit on each side for the seat bolts to screw in through the pad back into the frame. And it oversatisifed me! I drive a 13 Camry and it now feels like a high end luxury car. Can barely feel any bumps in the road what so ever, even at 90 mph can hardly feel or hear anything! If done right I highly reccomend! Doing trunk in the near future! Also from what another post said, yes the ends dont meet with each other but it's only like a quarter of an inch on each side, not a big deal what so ever very easy to cut to whatever suits your needs. And no it has no smell to it at all, or atleast mine didnt. But what did have a very big smell was the adhesive spray that I used. Not much of a bad smell over like a day or so it kinda has like a new car type smell to it. Not sure of the brand I used it wasn't what they offer i found it somewhere else but sure it smells somewhat of the same

Very thick so alot of trimming will be needed if you're putting this under your carpet. Your plastic panels might have a hard time fitting back in if you don't trim it to fit. I've dropped quite a few db's but it looks like I'm missing a couple more spots to fill. Mostly from the trunk area. Will buy more when it comes time but for now I'm quite happy with the amt of road noise I've killed off.I used my android phone with a db analyzer. I stationed my phone on my center console, a/c and radio off, and started driving 75mph. I did before and after. I also used second skin sound deadening material inside the doors and used gaskets around the doors to minimize air noise.Older model cars, like my 99 civic, weren't designed with the technology we have today. Doing my due diligence with sound deadening material really helped.

Second Skin Luxury Liner Pro does work, though it is a bit heavy, and the install can be a very tedious process. I was driving my 1st generation tacoma with all terrain tires on the highway for hours a day and started getting ringing in my ears and reduced sound sensitivity. I lined the interior in segments of dynamat, which helped bring down the amount of noises and rattling and made the truck sound 'dead' but the decibel levels were still into the 80's and 90's on the road. After installing LLP the levels are down into the high 70's to 80s most of the time. It's enough of an improvement that my hearing doesn't sound muted at the end of a drive anymore. I covered the back wall and floor only, it took 4 sheets, and it did add about 120 lbs to the truck, which I don't like. Doing the inner door skins would be great also, and I'm considering doing this next and seeing how much more reduction I see in the cab with a decibel meter. Initially I didn't want to spend what I did on this project, but its the proper way to get it done.

I used this on top of basic noise canceling and the difference is amazing. 2023.5 Land Rover Defender 90 doors.
