Reddit reviews TMS Mass Loaded Vinyl, 4' x 25' (100 sf) 1 Lb MLV Soundproofing Barrier. Highest Quality! Made in the USA

Sounds like you've chosen poorly.

Try this. https://www.amazon.com/Loaded-Vinyl-Square-Acoustic-Barrier/dp/B007N3356S

best way is to get rid of the things that are making the noise in the first place.

get a ssd if possible to get rid of the drive noise, use rubber vibration dampeners between any moving parts and your case(fans,hdd), get better case fans like the noctua NF-A14 PWM fans.

and if that does not help you, you will want mass to dampen noise, so go get some mass loaded vinyl

don't get the foam stuff it wont help as much as you think

hope this helps

I disagree with some of the comments. There's options you have to limit the soundwaves traveling through the walls. If you're in the cellar, there's a few things you can do to help the noise.

Mass Loaded Vinyl: https://www.amazon.com/Loaded-Vinyl-Square-Acoustic-Barrier/dp/B007N3356S

Subwoofer Pad: https://www.amazon.com/Auralex-Acoustics-SubDude-HT-Subwoofer-Isolation/dp/B00DI5AXNI/

Bass Traps: https://www.amazon.com/Column-Acoustic-Studio-Studios-Theater/dp/B01C9F83QQ/

Acoustic Panels (would recommend 2"): https://www.amazon.com/Pack-Charcoal-Acoustic-Absorption-Treatment/dp/B01KKNO9QW/

Now, the acoustic panels and bass traps are sound absorbers, not sound deadeners. In my opinion, however, if you get those last, it will improve the acoustics and accuracy of the sound you're hearing in your cellar, so maybe you wouldn't have to play it as loud.

I think the best thing you can do at first is get the subwoofer pad, followed by some mass loaded vinyl. Depending on the size of your speakers/monitors, you might want pads for those, as well. You're looking at reducing vibrations, which is what the pads and vinyl is made for. The foam and bass traps will just give you a more accurate sound.

The Knu CLD is a good choice. You may want to order an additional 14 sq ft just in case; you don't want to gut your interior then get stuck waiting for more CLD for a week. You can always throw the driver's seat back in and get to work with no interior though.

For CCF I'd recommend ensolite peel and stick from raam audio. I used this along with their BXT-II CLD tiles in my install and it's easy to work with. You'll probably need around 8 or 9 yards.

Finally for MLV I'd take the easy route and just buy this from Amazon. Should be more than enough.

Now, as an alternative, just contact the guy that runs sounddeadenershowdown.com. I've read that he is a nice guy and will help you select all of the stuff you need. The products he sells are top notch but I've heard shipping is costly. You don't seem that sensitive to price so this may be the way to go to ensure you get the right materials the first time.

Lastly, take a long look at your current install. If you don't have 1/0 gauge running to the back, 6 channel RCAs, two sets of wires run to each door, etc. consider spending the extra cash and doing all that stuff while you have the interior out.

I had good results on a full-sized van for about $350 using a box of Dynamat for $150 and a roll of MLV for $200. I was able to reuse the foam already on the floor.

I tried to get about a 30% coverage with the dynamat, focusing a little more on panels that sounded louder when I tapped them (like the wheel wells). I know in cost-is-no-object installs they go for, like, 120% coverage, but a more conservative approach seemed to work just fine for me.

I did 100% of the floor and up the firewall with the MLV, and then hung it most of the way up inside the walls. I didn't do inside the front doors because lazy, and also because on this vehicle the thin single-barrier door seals are the main source of cabin noise.

Good results for the money IMO, it makes my 1991 van sound a lot more like a modern vehicle. Road and exhaust noise is greatly reduced. I still get a lot of wind noise from those damned door seals, but you won't have that issue on relatively modern Excursion.

I don't have exp. with it but have heard mass loaded vinyl is good. Not sure how it compares to just hanging an exra sheet of drywall or layering a brick facade though.

I'm no expert on this, but have you looked into mass loaded vinyl? For example, https://www.amazon.com/Loaded-Soundproofing-Barrier-Highest-Quality/dp/B007N3356S

I've used mass loaded vinyl. I've used it personally. I bought so much of it, that it was delivered freight on a pallet and I needed a friend to help me transport the roll inside. It. Doesn't. Work.

If you want to buy it, knock yourself out. I even went through the trouble of finding a supplier for you. Enjoy.
