Kinetics KBC Sound Absorber/Noise Barrier Composites are thin, rugged, high-performing, flexible acoustical quilt and vinyl composites designed to solve noise control applications where sound absorption and sound blocking must be increased.
Kinetics KBC Sound Absorber/Noise Barrier Composites are available with 0.50, 1.0, or 2.0 psf (2.5, 4.9 or 9.8 kg/m2) mass loaded vinyl barriers with a quilted aluminum cloth faced fiberglass absorber on one or both sides of the barrier.
KBC-50RBQ and 100RBQ are used when a noise source is located on one side of the acoustical material. Sound originating from the source is initially absorbed by the quilted fiberglass and then blocked by the vinyl barrier. The reflected sound waves are further dissipated by the fiberglass absorber.
KBC-50BQQ, 100BQQ, and 200BQQ perform in the same manner as KBC-50RBQ and 100RBQ except that they are designed to absorb sound on both sides of the composite, with one side acting as a decoupling layer.
Kinetics KBC Composites can be installed free hanging or attached directly to a noise-radiating surface. KBC-50BQQ, 100BQQ, and 200BQQ are ideal as an internal lining on any rigid structure that requires significant transmission loss improvement. In this manner, the limp mass vinyl barrier is decoupled from the structure by the fiberglass absorber which allows the barrier to vibrate freely thus increasing sound transmission loss performance.
Vinyls and fiberglass facings are available in other colors. Consult Kinetics Noise Control for availability.
Kinetics KBC Sound Absorber/Noise Barrier Composites are ideal for many diverse industrial and OEM applications where both reverberation control and sound transmission loss are required. Industrial applications include enclosures, machinery cover linings, and additions to existing walls or barriers. Architectural applications include crosstalk barriers, room dividers, ceiling barriers, and pipe and duct wrap.
KBC-50BQQ, 100BQQ, and 200BQQ perform in the same manner as KBC-50RBQ and 100RBQ except that they are designed to absorb sound on both sides of the composite, with one side acting as a decoupling layer.
Sound Absorber/Noise Barrier composites shall be of the description and acoustical data listed in this brochure. Absorber/Barrier composites shall be model KBC by Kinetics Noise Control.
