Udderly Quiet™ Pyramid Acoustic Foam 4″ Charcoal (Case of 4)

999955 in stock



We first designed our Udderly Quiet™ Pyramid Acoustic Foam for recording acoustic. Then, we realized that anyone who needs to reduce the echoes in a room could enjoy its acoustic properties. After all, everyone appreciates good sound quality. Whether you want to become the next big star or get some peace and quiet, you’ll love our 4-inch charcoal pyramid foams’ reverberation (echo) reduction.

These Pyramids Don’t Just Look Cool

Udderly Quiet™ Pyramid Acoustic Foams sport a distinct 3D pyramid pattern. Have you ever wondered why professional acoustic foams like ours have this design? The answer: science. A pyramid shape maximizes the surface area of the foam. More surface area means more sound absorption. As a result, you can hear fewer echoes than if you used foam with a flat shape.

Our Quality Is No Bull

Don’t underestimate our product quality. We may like to make cow puns, but we take our acoustic foam materials seriously. Our herd makes every 4″ charcoal pyramid foam panel from professional-grade polyurethane. The thickness of the foam resists rips and tears. Its lightweight design makes it easy to install anywhere. Udderly Quiet™ Pyramid Acoustic Foams even keep their color better than other foams on the market.

Keep Sound Where You Want It

Our pyramid acoustic foams improve both recording and listening. They promote clear sound without echoes, and that appeals to both creators and consumers.
