Sound Enclosures are a highly effective means of reducing the noise emanating from industrial or mechanical equipment. Also known as noise control enclosures, acoustic enclosures, sound booths, steel enclosures, or machine and equipment enclosures these self supporting noise barriers enclose noisy equipment without limiting access or impeding machine function. We offer options such as acoustic rated doors and windows, fully removable wall and roof panels, passive or forced air ventilation packages, electrical and lighting, and turnkey installations. Common equipment applications include compressors, generators, blowers, hydraulic pumps, industrial fans, vibratory bowl feeders, routers, print presses, plastic grinders, and many other noise offenders. Let us design an enclosure to meet your noise reduction goals. ArtUSA Noise Control Products, Inc. Noise Control Barrier Walls are engineered, modular sound panels designed for high sound transmission loss of outdoor noise. Typical customers have chillers, substations, fans, blowers, compressors, air conditioners and other outdoor mechanical equipment cause disturbing noise at its neighbor's property line. Our engineered sound panels are specifically designed and constructed with environmentally durable composite construction that absorbs sound energy and shields offensive noises.

Over the past decade ArtUSA has designed hundreds of power plant noise control. Employing every type of combustion turbine such as the Siemens- Westinghouse 501G and the General Electric 9FA. We offer custom silencer designs encompassing the acoustical, aerodynamic and structural design along with materials selection, fabrication drawings, installation inspections and follow-up testing services.At the base load facilities, which are often the sole power supply for small but densely populated islands, noise suppression is frequently a major concern because there are few things louder than the super- charger on a huge industrial diesel engine. Consequently, we have been involved in the acoustical design of numerous diesel halls where containment of noise from the equipment inside requires attention to not only the building itself but also to the cooling air ventilation intakes and discharges, particularly when fans are required. We have built enclosures on dozens of large coal, oil or gas fired power stations in the United States and Overseas. Our typical work scope includes the design of all required noise abatement features, and the testing of the completed unit. These plants are large, complex and contain many more significant noise sources than other types of power plants. Our extensive field experience at these facilities allows us to easily handle even the largest projects.

Our engineers are intimately familiar with operational mechanics of these facilities, with all of the component systems and, most importantly, with the typical noise emissions of every source. This experience enables us to predict what noise controls and in what optimal combination will

Sound Barrier Walls

Outdoor community noise problems may require an engineered Sound Barrier Wall. Our walls offer sound reduction by absorbing the sound at its source and blocking the noise from transmitting to noise sensitive areas. Substations, HVAC Chillers, Power Generators, Cooling Towers, and Compressors are a few outdoor noise candidates for our Noise Barrier Walls.

Features:

• STC ratings of 26-30

• Passes FMVSS 302, UL-94

• Easy to cut and install

• High and low temperature applications

• Accepts matching tape

• Quilted fiberglass decoupler available

• Good corrosion resistance

• Meets Class A flammability rating per ASTM E-84

Typical Applications

• Noisy Pipes
• Duct Work
• Sheet Metal
• Heat Exchangers
• Valves
• Custom Acoustical Jackets

Features

• Available with a 1" or 2" quilted decoupler
• Meets Class A flammability
• Suitable for indoor or outdoor applications
• Easy to cut and install
• ArtUSA flexible lag series combines a loaded vinyl barrier with foil facing on one side. When a quilted fiberglass is added to the lag barrier it acts as a decoupler to form a tight fitting "floating" noise barrier.

How Noise Barriers Work

The "nuisance" noise is "diffracted" over barriers increasing the distance it must travel to the listener.

Reflection & Absorption

The effectiveness of a barrier depends on how well it diffracts and absorbs the noise.

A high performance barrier has negligible noise transmission and reflection. This is controlled by two coefficients: Absorption() and Sound Insulation (R).

Quality Noise Barriers

• significantly reduce the noise levels.
• guarantee acoustic performance.
• significantly reduce public complaint levels.
• provide an aesthetic visual barrier that will last.
