Description
In contemporary buildings, noise emanating from building construction systems might give rise to grave concerns. Generally speaking, noise produced by a particular source or sources falls into one of two primary categories:
Any sound that passes in the air, such as HVAC ducts, music, human speech, and traffic, is known as airborne noise. Airborne sound waves reverberate (or create excessive echoes) in enclosed spaces like inside building areas and closed-off rooms. This raises the perceived noise level in the enclosed region and can spread to neighboring places that are sensitive to noise.
The sound that is transferred from a vibrating source is known as structure-borne noise. The building’s structure absorbs the energy created by these vibrations, whether it is through the HVAC ductwork, plumbing and pipework, walls, ceiling, or structural supports. Via the solid structural elements of the structure, the energy easily moves throughout it. At different points along the way, it radiates outward as noise in the atmosphere.
HGR Silencer Composite Panels are made of a thick layer of HGR sound-absorbing melamine foam sandwiched between a flexible 1 lb/ft reinforced sound-isolating, or blocking, mass-loaded vinyl. When combined, the layers lessen the amount of sound that is transmitted overall by isolating and absorbing mid-to high-frequency noise. For optimal control of undesired sound, a melamine foam decoupler layer is integrated into the Composite Sheet to create airflow between the mounting substrate and the sound-isolating barrier layer. For the best possible sound outcome, the decoupler helps to structurally isolate the barrier from the vibrational acoustic energy carried by the structure.
Because our Composite Panels are fiber-free, handling them won’t cause any problems, and they can be easily cut to any size to make installation easier. HGR has a peel and stick PSA option for even easier installation; simply create the required field cuts, remove the backing, and stick or direct-apply the Composite Panels to substrate.
