Sound Seal manufactures two types of Noise Barrier Composites, the Barrier Septum Composite (BSC) and the Barrier Backed Composite (BBC).
Sound Absorber & Noise Barrier in One
Features
Sound Seal noise barrier composites offer maximum noise reduction by combining a sound absorber and noise barrier in one.
Applications
Typical applications include acoustical liners, jackets and wraps, curtain panels, bound or un-bound rolls and die-cut pieces.
Benefits
Flexible composites can form to any shape, and are fire safe and low smoke emissions per ASTM E-84, Class 1.

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.
