Echo Absorber™ Acoustic Panel (Natural Blend – 1″x2’x4′)

Introducing the Echo Absorber™ Natural Blend 1x2x4 Acoustic Panel from Soundproof Cow. Made with 80% recycled cotton fibers, this 1-inch-thick panel is eco-friendly and offers enough sound absorption for many commercial and residential applications. The panel holds a 0.65 Noise Reduction Coefficient, meaning it absorbs 65% of high, middle and low frequencies from any source. Use this panel in any restaurant, amphitheater, office, home or other space to facilitate a tranquil environment. Additionally, our PL® Construction Adhesive allows for easy installation on any flat or curved surface.

Echo Absorber™ panels are designed with thermally bonded construction. They are also touch-safe since they don’t contain volatile organic compounds (VOCs) like formaldehyde. These panels are mold-resistant and Class ATM-rated for flammability as well, making them compliant with any stringent building codes.

Each 1x2x4 acoustic panel provides 8 feet of sound-proofing coverage. Order your Echo Absorber™ products from Soundproof Cow today!

Echo Absorber™ acoustic paneling is one of our most cost-effective soundproofing solutions. However, at Soundproof Cow, affordable doesn’t have to mean cheap — Echo Absorber™ panels offer exceptional quality at a reasonable price point, making them perfect for DIY applications or for anyone else who wants to make the best use of their budget.

A Natural Alternative

Echo Absorber™ natural blend paneling is made from genuine cotton fibers, as much as 80% of which are recycled. It contains no VOCs or hazardous materials and has a Class A fireproof rating. As a result, it can be installed in locations where strict building code requirements prohibit the use of polyurethane or other synthetic materials.

Superior Performance in a Lightweight Package

Echo Absorber™ acoustic panels are more than just environmentally friendly — they’re also one of our best soundproofing materials. Use them to deaden recording spaces and prevent outside noise from bleeding in. Echo Absorber™ panels are also highly effective at absorbing nuisance reflections that cause poor sound quality.

Working with our echo-reducing panels is easy. Echo Absorber™ acoustic panels can be glued to any flat surface using our PL® Construction Adhesive. Alternately, install them inside a wall for soundproofing purposes. As an added bonus, they also provide excellent thermal insulation properties, making your space more comfortable and even potentially lowering your utility bills.

Echo Dampening Panels Ideal for Home and Professional Use

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
