6 Pack 12" X 12" X 2" red acoustic sound foam studio panels, 15 sharp wedges - Remove Noise & Enhance Sound Quality by-beefoam

I have not got my project totally done yet, but it seems to be working really well. I used 2 inch thick styrofoam wrapped in blue burlap and then attached these acoustic panels using 3M adhesive to one side. This then slides up to the door opening with door shut. This just about kills all the sound coming from the living room (2 babies till 9:00) sometimes crying sometimes screaming. Have to get up early so I go to bed at 7:00 PM

Does not reduce noise what so ever. It's normal packing foam cut to have a spiked shape. It's too lightweight to absorb any sound. Save your money.

Overall its not bad unless you're just starting out this would be a good option,

Haven't placed them yet, but as someone who has used top quality acoustic foam, this feels nothing more than a large sponge. once it's up, I will revise this and report back.

Exactly what I had hoped for! Great product, It's perfect for extra soundproofing in our new home /recording studio. Product came fast and was packaged well. Great buy, will be ordering more!

Working great

It came as advertised and so far seems to be what I was looking for

Just like the add.
