I have no way to measure exactly how much they really reduced the sounds of my case's fans, but an anecdotal guess would be about a 30% reduction. Nothing can really silence the 6000 rpm fans in my case, but this foam does help.The adhesive side was very nice and sticky. Applied easily and was difficult, but not impossible, to take back off.The foam I received looks exactly like the product pictured. This appears to be the most basic kind of sound absorbing foam, though. The tiny dimples on the surface don't do as much as deeper dimples can, but deeper dimple foam wouldn't fit in my computer case anyway. ### ⭐⭐⭐⭐ Works well. *by C***K on November 15, 2011* I am using the foam on the inside of a hollow metal apartment door. I covered the entire inside of the door with the foam panels, which took 7 panels. I was lucky with the width, 2 panels wide at 36" was perfect. I only needed to cut the bottom which took 1 panel cut in half, which cut very easy with a razor. I removed all the locks from the door and cut holes through after. I have a dead bolt that only locks from the inside, was able to just reattach to the door and compress the foam. Sound is down drastically both ways, don't expect miracles though. For the price and ease of use got 4 stars out of me. The foam has been upf for around 8 months now, glue is still holding. Very happy with my purchase overall. ### ⭐⭐⭐ One color not two. *by A***F on January 11, 2013* Color of product is grey, not two toned. Is light weight and easy to cut and use. Looks like good quality. ## Frequently Bought Together - Sonic Barrier 1/2" Acoustic Sound Damping Foam with PSA 18" x 24" - Sonic Barrier 1" Acoustic Foam w/PSA 18" x 24" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/2343982-1-2-acoustic-sound-damping-foam-with-psa-18-x](https://www.desertcart.us/products/2343982-1-2-acoustic-sound-damping-foam-with-psa-18-x) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
