**Egg-Crate Design Offers Superior Sound Absorption** The principle of acoustic foam is that when sound contacts the foam, a portion of sound is reflected, while other sound waves enter the foam, where they undergo friction and react with the sound-absorbing material, generating heat. Compared to other shapes, the benefit of the egg crate shape lies in its greater surface area for sound reflection and its intricate network structure that creates better conditions for friction and heat generation. **Strong Adhesive & Simple to Install** Unlike other acoustic foam panels, these come with a strong adhesive backing.

It's time to decorate your own room or studio! **Fire-Resistant and Safe for Indoor Use** These soundproofing panels are well-suited for indoor usages.
Fire rating: Passes California Technical Bulletin 117-2013.
