Sound Seal’s exterior barrier backed composite products, or BBCs, consist of a vinyl coated fiberglass cloth faced quilted fiberglass absorber bonded to a reinforced loaded vinyl noise barrier. “X” Style curtain panels are typically constructed with grommets across the top and bottom and exterior-grade Velcro seals on the vertical edges. Rolls measuring 54" x 25' are available with edges bound or unbound.
Applications
Sound Seal’s heavy duty, weather-resistant Sound Curtains Panels can be used in an array of permanent and temporary outdoor applications for construction site noise control.
Sizing
All curtains are custom made with standard sizes of 54” x any desired length up to 25’ with up to a 2” thickness. Custom curtain sizes and bound or unbound rolls are also available.
Easy Install
With grommets across the top and bottom of the product, and Velcro along both sides, BBC curtains are easily hung, and moved, as needed.
Acoustical Performance
BBC products can offer up to an STC of 37 and an NRC of .85.

Decibel Examples
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.
