Sound Dampening Foam

Whether you’re setting up a budget bedroom recording studio, putting the finishing touches on a world-class production studio, or an audiophile’s dream home theater, you can always use more foam. After all, a poorly treated acoustic space can really put a damper on an otherwise great recording.

It's also practically impossible to get a trustworthy impression of a mix over monitors without treating your space. Luckily, it’s pretty easy to make a world of difference with sound dampening foam even when you’re on a budget. With this 6-pack of sound dampening foam tiles, you'll be well on your way to improving the acoustics of your recording, or listening spaces.

Easy Setup

These two inch thick one-by-one foot square panels make it easy to customize the perfect reflection fighting setup for your space. If you can bribe a friend to help you out, and you have a mirror handy, you can easily treat your room in a quick afternoon project. Sit in your normal listening position and have your buddy walk around the perimeter of the room with the mirror facing you. Any position where you can see your speakers or monitors is a reflection point. Place a foam tile in each of these positions and you’ll drastically reduce mid- and high-frequency echoes and reverberations in your space.


One benefit of these sound dampening tiles is that you can really dial in how "live" or "dead" your space is: striking just the right balance between reflective and absorptive surfaces in your space is just a matter of putting up less or more tiles. If you want to get really adaptive and flexible, consider mounting your tiles with Velcro so you can easily find the sweet spot.

NOTICE: We ship Silverback Sound Dampening Foam in vacuumed sealed packaging. Because of this, the foam sometimes takes time to expand to its full size and volume. If the foam does not expand well on its own within a day, soaking it briefly in water, wringing it out (like a sponge) and air drying for 48 hours will help it expand properly.
