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.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend Soundproofcow.com to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
