SonoCon Sound Control Materials Sound absorbing materials are fibrous or open-cell structures that reflect very little acoustical energy. Instead, sound waves passing through the materials cause the internal strands or membrane material to vibrate. This resulting mechanical movement dissipates the acoustical energy in the form of heat. Sound absorbing materials reduce the reverberant noise build-up from inside buildings, rooms, and enclosures and provide a means for the energy to decay.
Sound barrier materials block noise. Instead of absorbing energy, the materials block the noise path and reflect the sound away from the barrier. The efficiency of any material as a noise barrier is directly related to its mass and density. As mass increases, so does the sound transmission loss characteristics.
To optimize noise reduction performance, SonoCon™ Softwall Composite acoustical barriers and enclosures incorporate both material properties into relatively thin, light weight panels. Cost effective, durable and easy to install, SonoCon™ Softwall Composite structures are impervious to moisture, oils and many industrial chemicals.
SonoCon™ Softwall Composite enclosures and soundwalls offer an economical alternative to rigid acoustical panel systems. Panels can be supported from existing structures, angle or pipe. Sliding and accordion panel systems can be installed to permit quick access to equipment and processes. For many applications, these acoustical enclosures are furnished with an open top to allow natural ventilation and use of existing lighting and fire suppression systems. Actual noise reduction is related to the height of the barriers and proximity to the noise source and the adjacent work area.
Several panel systems are available to match both acoustical and physical requirements. Options include viewing ports, sliding acoustical access panels, barrier panels absorptive both sides, acoustical roof panels, overhead suspended acoustical baffles, silenced ventilation openings, heavy-duty long-span steel support systems, standard and rolling acoustical screens, ASTM E84 Class A fire rated assemblies.
Acoustical Performance Transmission Loss (TL) of the acoustical panel assemblies shall be determined by the dual reverberation room method by an independent acoustical laboratory in accordance with ASTM Specification E-90 or latest revisions thereof.
Sound absorption coefficients of the composite panel assembly when tested by an independent acoustical testing laboratory in accordance with the requirements of ANSI/ASTM C423 and E-795 or the latest version thereof shall be equal to/or greater than those.
Structural Performance Enclosures shall be engineered and erected in accordance with the structural requirements of the Uniform Building Code (UBC). All mechanical equipment, electrical devices, and their installation shall be as required by the National Electrical Code (NEC) and local building regulations.
SonoCon Septum Panels SonoCon Septum Panels are used to construct sound attenuating enclosures and noise barriers under conditions demanding both substantial noise reduction and structural characteristics. The SonoCon Septum panels are particularly effective at reducing the noise levels at those frequencies which interfere with intelligible speech.
