BXI Double Noise Blocker Sound Proof Foam, 39.4 X 13.4 X 1 Inch Egg Crate Foam Rubber Sound Deadening Material, Dampening Acoustic Foams Panels for HVAC, Pipe, Machine, Window, Wall, Door

Came in handy

It doesn't work! It's very thin, according to Amazon's description. This is an inch thick, but it's not!

Good material and easy to trim, using it to lower compressor noise from portable ac, and so far good my use.

Not a miracle worker, but did help drop the db with my noisy central air compressor.

I have a Black and Decker washer, and I needed to make it quieter since I live in an apartment. I used 4 of these around it, and it blocks some noise but should be better for the price.

I couldn't be more pleased with this product, it lets me sleep well at night. Here is the thing, I have my kids bathroom adjoining our master bedroom, with their faucets in the wall between. Despite telling them to shower early, they would invariably get into the shower late in the night (yea, teenagers, right??), and the loud noise from the faucet would really disturb my sleep. Very annoying. Well, recently we had to open the wall to detect a leak (story for another day), that's when I saw the opportunity to insert sound proofing around the faucet and found this product on Amazon. Frankly, I wasn't expecting it to make a big difference, but lo and behold, after the installation and sealing the wall, the loud rumble of the faucets is reduced to a faint muffle that is hardly noticeable. Wow! I can sleep again at night, and best of all, don't have to get into a fight with my kids about when they should use the shower :)))).

The roll came with a horrible odor that is still lingering months after purchase.

I bought this to make a window plug for my bedroom window. My neighbor has been terrorizing the neighborhood for months with his HEMI engine at all hours, and this is my last ditch effort to try and get a full night's sleep.I had tried butyl on posterboard first, but it was a major failure. The butyl was way too heavy and didn't provide the sound dampening I needed or expected. Ended up being a complete waste of money. Not something I would recommend for anyone trying to build a window plug, unless you're using wood (not cardboard) and are prepared for a heavy lifting session every time you put the plug in the window.This acoustic foam ended up doing the job way better and makes a much lighter weight plug. I took the extra step of sealing off the edges of the window with gaffer tape, and between that and the foam plug I haven't been awakened by street noise.I used the recommended 3M mounting tape to install the foam vertically onto posterboard the height of the window (36"). I positioned the product as such that foam protrudes from either edge, to make up for the fact that the window is 51" wide but the posterboard is only 48" wide.I had to trim the foam a little bit, and use the scraps to fill up any gaps or cracks when I lift the plug into the window each night. My bedroom is almost completely light tight and so far I haven't been awakened by the demon car since using this setup.🤞🏻I'm giving 4 stars because it isn't perfect, but it's close.I'll update if anything changes.UPDATE: It's been a few weeks and this stuff has completely changed my sleep. I am no longer awakened at all by street noise or the demon car! Increasing to 5 stars because it did what I bought it to do.
