 | 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.

 | Schema Architectural Absorption Panels
High performance sound absorption and reverberation control
SCHEMA Series acoustical panels can be matched to most any interior providing better acoustics and reducing distracting noise.
Noise reduction coefficients (NRC) range from 0.55 to 1.15 to meet the most rigorous acoustical requirements.
SCHEMA Series acoustical panels are manufactured in sizes to 48” x 120” and in thickness varying from 3/8” to 2 1/8” to suit the architectural and design standards.
SCHEMA Series panel finishes include polyester fabrics, vinyl sheet, and architectural metal and wood facings.
SCHEMA Series panels are Class A fire rated and come in a wide selection of finishes and color options, custom fabrics and/or customer’s own material can be used.

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 Industrial Silencers
Silencers are installed in the gas stream to reduce both blower generated noise as well as noise which is being created upstream or downstream of the blowers. Silencers can be installed at a blower inlet, at the blower discharge, within the ductwork or at the duct termination point such as exhaust stacks or inlet plenums. Round or rectangular, silencers can be fabricated in most any configuration as needed to meet space, attenuation and allowable pressure drop constraints. In general, increasing silencer size will increase attenuation and decrease its added resistance to airflow. Further, locating the silencers at some distance from the blower equipment and away from elbows or turns, and locating the silencers where flow of air is fairly laminar will minimize added resistance to airflow. |

 | SonoCon Class 3 Preassembled Noise Control Structures
SonoCon™ Class 3 acoustical panels provide both significant sound transmission loss performance and sound absorption characteristics. These properties used together effectively reduce the noise levels by eliminating the reverberant buildup of acoustical energy within an enclosure, eliminating reflected energy as a source of multiple sound paths, and acting as an effective barrier to the passage of sound.Advantages :-
SonoCon™ Class 3 acoustical enclosures and soundwalls ship complete and ready for setting into place. - Shorten installation times and minimize disruption.
- Factory applied special coatings provide durable and attractive finishes.
- Unitized assemblies meet Code structural requirements.
- Integrated silencer ventilation systems are sized for the equipment, application and use.
