Sound Seal’s barrier backed composite products, or BBCs, consist of a reinforced loaded vinyl noise barrier bonded to fiberglass that is quilted with a vinyl-coated- fiberglass-cloth facing. Curtain panels are constructed with grommets across the top and Velcro along the vertical edges. Rolls are available 54" wide x 25' long and can be supplied with edges bound or unbound.
Applications
Typically used as modular curtain panels in acoustical curtain enclosures where abuse resistance and excellent durability is required. Also used as sliding acoustical doors, as durable acoustical jackets on fans or as sound curtain panels on outdoor construction projects. This composite material absorbs sound within an enclosed space and reduces the transmission of noise from that space.
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 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 32 and an NRC of .85, helping to contain noise to its source and improving the overall acoustics of a space.

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.
