Noise Control Enclosures

A highly effective means for controlling localized industrial noise is to install an encapsulating noise control enclosure to contain and absorb noise where reduced sound levels are required. Because almost every in-place noise issue is in a different environment, each application is a custom design.

How does SysTech address these issues? This is what we do…

There are two (2) basic categories of enclosures based on construction. Both are used in sound enclosure applications such as:

  • Containment of machinery
  • Process enclosures
  • Facility dividers
  • Movable screens
  • Engine housing
  • Compressor/pump/fan enclosures
  • Factory quiet areas
  • Control rooms

Noise Control Curtain Systems

Attaching flexible curtains to a tubular frame assembly provides an efficient noise control system. The soundproofing curtain systems are an economical, high performance, noise control product possessing high mechanical strength. They are fire safe, easily cleanable, resistant to dust, dirt, oils and most chemicals, and give a long service life. Curtains reduce reverberant noise energy and offer a 7-10 dB reduction. Curtain enclosures sometimes referred to as “softwall” noise enclosures, are available which combine a high-mass noise control barrier with a lightweight acoustical fiberglass absorber, are designed to both contain and absorb noise, and offer an average of 12-15 dB reduction. Options include:

  • Grommets and/or Velcro on edges
  • Steel framing (self-supported or ceiling mounted)
  • High-temperature and outdoor facings
  • Decorative facings
  • Standard or custom colors
  • Clear view windows
  • Roof systems
  • Access panels and doors
  • Vent kits
  • Tracked panels for quick movement

Benefits of a noise control curtain enclosure include:

  • Quick access
  • Replacing a damaged panel is quick and easy
  • Movable
  • Durability – with chemical and oil resistance
  • Cost-effectiveness – compared with metal enclosures
  • Easy assembly – no special installation required
  • Flexibility – movable and reusable
  • Fire safety – with low smoke configurations

Noise Enclosures

Another effective means to attenuate a noise source is a rigid metal enclosure. Our standard wall panel is constructed of an 18 GA solid exterior skin with a 22 GA interior perforated liner, and a 4 lb/cu. ft. density acoustic fill core. Options for other types of wall construction are available. With a Standard Tempering Core (STC) of up to 41, metal enclosures are designed to both contain and absorb noise, and to act as a barrier between noisy and quiet areas. Attenuation expected is 20 to 25 dBA. Options include:

  • Clear view windows used to view machinery in operation
  • Roof systems
  • Ventilation systems for heat removal
  • Louvers and ventilators
  • Access panels
  • Single or double seal doors
  • Custom cut-outs to accommodate existing gauges, hoses, valves, and conduit
  • Outdoor and high-temp models available

Noise Enclosure Panels for Air Handling Units

Noise control for air handling units can be applied to reduce the sound levels from the air handler fan.  The air handler’s sides and top would have double wall construction with internal fiberglass insulation. The noise enclosure panel thickness would be based on attenuation requirements.  Along with the walls, the inlet and outlet duct from the air handler would be evaluated and treated as required.

SysTech offers both standard and custom designed sound enclosure systems and can help you to determine the best sound enclosure option to suit your needs.
