Absorbers are porous materials made of either foam or fibers used to line hard sound- reflective surfaces to reduce airborne noise.
Our Acoustic foam; which is often referred to as sound absorbing foam or soundproof foam, is available in a variety of thicknesses and facings that can be customized for a specific sound or purpose for functional and aesthetic purposes.

Frequently Asked Questions
Are absorbers cost effective?
- Yes, absorbers are a very cost-effective solution to many airborne noise problems. They are typically used to line the inside of any hard-sound reflective enclosure and they break up the sound field and reduce the noise problem.
What are some common applications?
- Generators, compression housings, engine compartments, cowlings, pumps, and device enclosures. Absorbers can work inside operator compartments or cabs for they can reduce the noise levels, improve speech intelligibility and reduce hardness, therefore, increase general productivity and increasing alertness.
What is Absorption?
- It’s eliminating the reflection of sound waves within an environment. Reflected noise makes an environment louder. Typical absorbers are manufactured from various foams or fiber materials.
What is an Absorber?
- An Absorber is any material that has an open cell structure or porous fiber structure that can be used to line hard enclosures or other rigid surfaces in order to reduce reflected sound energy.
How does an Absorber work?
- In order to understand how an Acoustic Absorber works we must first understand what sound is. The sound is nothing more; or less than a pressure wave moving through a medium ( typically air in this case). Absorbers work by dissipating the pressure wave. The absorber takes in the sound energy and converts it into heat within the cell or fiber structure; don’t worry the overall created is tiny – you won’t be heating your house with it.
How do we measure sound?
- Sound typically measure in decibels.
What are the common sound decibels?
- Threshold of hearing – 10 DB
- Soft Whisper – 35 DB
- Large Transformer at 200′ – 55 DB
- Speech at 1′ – 70 DB
- Pneumatic Drill at 50′- 85 DB
- Subway Train at 20′ 95 DB
- Pneumatic Hammer at Operator – 105 DB
- Jet at Takeoff at 200′- 120 DB
