Echo Absorber 1″ Natural Blend Acoustic Panels

1” thick Echo Absorber™ panels are our thinnest and most economical solution for high- and low-frequency sound reduction. With their low profile, they’re unobtrusive in small spaces and easy to install using our PL® Construction Adhesive.

Good for the Environment, Good for Your Health

Natural blend acoustic panels are made from 80% recycled cotton fiber and are VOC-free, mold- and mildew-resistant and Class A fire rated. They will not cause skin irritation when touched. Because of their density, they also have excellent thermal insulation properties and can actually make a room more comfortable, in addition to providing soundproofing against low-frequency noises.

Echo Absorber panels are sold by the sheet. 4’ by 4’ panels provide 16 square feet of coverage and can be cut or shaped to fit the dimensions of any room. 2’ by 4’ versions are also available in 1” and 2” thicknesses.

Typical Applications

When installed properly, 1” Echo Absorber panels have a noise reduction coefficient of 0.65, which means they absorb 65% of sounds across the frequency spectrum. This makes our 1” panels a good choice for soundproofing an office, gymnasium or other space with a lot of ambient noise. Though less ideal for recording studios, they do provide some level of low-frequency sound reduction and will absorb many of the nuisance reverberations that can muddy a recording.

Customer Reviews

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