If you’re recording a song, doing a podcast or in some other situation where low-frequency bass sounds can ruin your operation, you need to make sure you’re in a clean sound environment. That can be difficult if you’re working in your own home studio or other recording environment that may not have the best acoustics.

A great solution is acoustic foam that’s specifically designed to trap those kinds of sounds. The problem is that the standard bass-absorbing foam may not fit everywhere, particularly the corners of your studio where sounds can bounce around and create interference the most.

The ideal solution, especially if you have a somewhat larger room that may have a lot of low-frequency sounds to absorb, is the Soundproof Cow Class A™ Corner Trap 48” in gray. Each 48” grey corner trap foam order comes with four traps — one to fit neatly in each corner and quietly absorb sound. The neutral gray color allows these traps to blend in with virtually any environment.

Another challenge those trying to soundproof their studio may also face is the fact that most acoustic foam is not particularly resistant to heat or flames, which means the building codes may prohibit a lot of foams from being used in some studios.

Fortunately, that’s not something you’ll ever have to worry about when you order the Udderly Quiet™ 48” Class A™ Corner Trap from Soundproof Cow. These traps have a Class A flammability rating, which means they have much greater fire resistance. They’re made of a melamine foam that’s still highly effective at dampening unwanted sound but that stands up to heat and flame much better than traditional acoustic foam. Our 48” grey corner trap foam will pass most building fire code regulations for exposed materials.


Engineered for performance — Udderly Quiet™ Class A™ Corner Trap is a free standing, triangular column that fits into room corners. It is a thick melamine foam product with vertical fluting. The fluted pattern was designed to trap hard to control low frequencies.

Quality — Udderly Quiet™ Class A™ Corner Trap Acoustic Foams are made from the highest quality melamine foam. This foam is consistent in density and firmness so acoustic performance will also be consistent.

Ease of Installation — Udderly Quiet™ Class A™ Corner Trap Acoustic Foams are light weight and can be either free standing or mounted to a variety of surfaces. No special tools or materials are needed.

Architectural Interest — The bold, fluted pattern of the Udderly Quiet™ Class A™ Corner Trap Acoustic Foams creates a visually unique and professional environment.

Flammability — Udderly Quiet™ Class A™ Corner Trap Acoustic Foams are manufactured from melamine foam that has a Class A™ flammability rating. This product passes most building code flammability requirements for exposed materials.

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
