Sound Proof Material Products
Incredibly versatile when applied to enclosure walls, ceilings, hull
walls, carpet underlayment. Multiple thicknesses allow creative solutions for almost any problem
area.
GSI has a wide range of sound proof material products which
can be modified to your engineering needs. Foam thicknesses from 1/4" to 2", available
in a variety of facings, barrier densities and pressure sensitive adhesive backings. Die cut parts
can be made to fit your specifications.
GSI provides the additional benefit of thermal insulation margins.
For added safety, all materials are fire retardant.
What is noise and why Is it harmful?
Noise is quite simply undesirable sound. It is irritating and harmful
primarily because of its intensity. At increased intensity sound energy becomes noise and physical
as well as psychological harm can occur in humans when exposed to noise for periods of time depending
upon the intensity. Physical harm to human beings is easily recognized and measured. Psychological
harm although difficult to measure can result in reduced worker efficiency both in quality and
quantity of work produced.
How we approach your noise problem
We begin with a basic understanding of the fundamental properties of
noise. A noise source produces noise as radiating sound pressure waves, which travel through the
air in all directions. We can measure the intensity and calculate the frequency distribution curve.
We know that noise radiates from a source and travels along a path to a receiver, the human ear.
Using this concept of source-path-receiver we then can formulate various approaches to solving
your noise problem.
DESCRIPTION: 1/4" thick foam Decoupler, 1 lb. per sq. ft. Barrier,
¼" or ¾" foam absorber faced with fiberglass reinforced aluminized mylar. All materials
are fire retardant. For use where motor enclosures are thin having relatively little mass.
APPLICATION: GSI should be applied on enclosure
walls and ceiling and should not touch engine. GSI can be applied to hull walls inside
stateroom to absorb noise and provide thermal margin. Use OSI Sound-Stop ½" thick as a carpet
underlayment.
ADVANTAGES: GSI will reduce noise levels by minimizing noise
reverberation. GSI has a 1 lb. per sq. ft. mass barrier, which yields at least 19 dB
STC rating for noise transmission loss. Acoustical foam faced with aluminized mylar means improved
aesthetic shiny appearance reverberation elimination and thermal insulation margin.
