All Noise Control Sound Curtains
All Noise Control manufactures heavy duty, weather resistant Sound Curtains for outdoor applications. We offer modular panels that can be used for short-term or temporary applications such as construction sites or drilling operations as well as long-term permanent applications such as HVAC systems, dust collectors and generators.
The Difference between Sound Absorption and Sound Blocking
The Difference between Sound Absorption and Sound Blocking
Sound is like water. It doesn’t have a shape or form, but molds itself to its surroundings. And like water, sound can be absorbed by some materials and contained by others.
Noise Control Frequently Asked Questions
We have listed below some of the most common questions and their answers in hopes of providing basic knowledge related to noise, and noise control products and systems.
ABCs of Noise Control Materials
Noise Absorption Sound absorbers are soft, porous, open-celled materials such as foam sheets or fiberglass blankets and baffles that reduce the reflection of sound waves. Their sound absorption efficiency is rated by a “NRC” number – Noice Reduction Coefficient*. The HIGHER the NRC rating, the more EFFICIENT the product is at absorbing noise.

*NRC is a sound absorption rating. It measures a percentage of how much sound will not be reflected back from where it came. Based on a range from .05 to 1.0, where a NRC of 1.0 means that all the sound energy that hits that product passes through it and does not “bounce” back to its source. A NRC of .60 would reflect 40% of the sound back to the source and let 60% of the noise pass through it.
