Noise Reduction Enclosures and Barrier Walls

dB Noise Reduction® Inc. designs and manufactures custom Noise Reduction Enclosure Systems for a wide variety of applications including:

• Control rooms
• Fans
• Pumps
• Generators
• Industrial Equipment
• SCIF's
• Test Cells
• Engines and Motors
• Process Controls
• Controlled Assembly

Equipment enclosures can be provided with fully silenced passive and powered ventilation packages, air filtration, acoustic man and equipment doors, acoustic windows (up to studio quality where required) equipment and piping penetrations, and many other accessories as required. Panels can be "tuned" for appropriate sound attenuation as required and are available in steel or stainless steel with factory finishing or field painting options. Small enclosures can be shipped fully assembled while larger enclosures can be shipped flat-packed for easy field assembly with the interlocking panel system. While systems are made to be universally simple to install anywhere in the world, local installation by factory technicians may be an option. Consult with us to determine your best solution.

Acoustic Barrier Wall Systems are available as both ground and rooftop mounted systems - and either on may be fixed or floating, depending on requirements. These wall systems act as an architectural (visual) barrier, but more importantly they are engineered to be high performance acoustic barriers that break the line-of-sight to both absorb noise on the equipment side while blocking its transmission through the "quiet" side. Acoustic Barrier Wall Systems are designed in accordance with Fresnel equations and tested acoustic performance values of the materials to factor the noise from the equipment as well as various environmental elements in the area, since these have a discreet effect on the way sound propagates and are specific to that location. Effective wall height and distance from equipment are vital factors to ensure successful noise mitigation, ease of access to equipment, and appropriate aesthetics to enhance both the visual as well as the acoustic environment.
