OSP-2 is a Class A fire-rated, modular outdoor sound panel designed to absorb and block unwanted noise in temporary and changing environments. Ideal for construction sites, oil and gas operations and other industrial applications, OSP-2 provides a practical alternative to permanent noise control systems.

Available in 54" x 104" and 54" x 54" standard sizes for streamlined fulfillment. Product measures approximately 2” thick.
Perimeter grommets allow for easy installation, repositioning, and mounting on walls or scaffolding in either vertical or horizontal orientations to meet changing site requirements.
An STC rating of 18 and NRC rating of 0.70 can be achieved with our OSP-2 Outdoor Sound Panels.
Class A fire-rated and built to perform across a broad range of frequencies, OSP-2 is an industry standout. Explore the charts below for detailed testing information.

Industrial-grade perimeter grommets allow for quick, easy installation using common zip ties. Mount OSP-2 vertically or horizontally on fencing, walls or other outdoor structures.
When trying to enclose a piece a machinery, most people will know they want it "quieter," but can't put into acoustical terms the end result (or decibel reduction) they want to achieve. With our audio examples, you can actually hear the decibel differences compared to static pink noise.
Pink Noise
An example of a randomized static pink noise. Pink noise uses deeper sounds and lower sound waves.
3 dB
Just perceptible. 3dB reduction has a 18% reduction in the perceived volume and yet is just barely perceptible to the human ear.
6 dB
Noticeable. 6dB reduction has a 34% reduction in the perceived volume and is very noticeable to the human ear.
10 dB
Double/Halving. 10dB reduction has a 50% reduction in the perceived volume and sounds half as loud to the human ear.
20 dB
Much more/less. 20dB reduction has a 75% reduction in the perceived volume and most noticeable to the human ear.
