4 WAYS TO QUIET A NOISY MACHINE

Product Testing & Information


Treat The Room

Treat the Room

  • Maximum Noise Reduction: 6-9 decibels (30-40% decrease in loudness)
  • Advantages: No inconvenience to workers
  • Disadvantages: Almost all of the room must be treated regardless of the size of the noise source.
  • “QFA” – Quilted Fiberglass Sound Absorption Products, Polywrap Baffles or Sanitary Baffles, depending upon specifics of application.

Treat The Wall

Treat the Wall Behind the Noise

  • Maximum Noise Reduction: 1-2 decibels if noise source sprays noise out into room, 4-6 decibels if noise is sprayed directly onto wall (such as noisy vent on the back of a machine).
  • Advantages: No inconvenience to workers
  • How much QFA? Treat the wall behind the machine with about twice the square footage of the “noise shadow” of the machine on the wall.

Build a Barrier or Partial Enclosure

Build a Barrier or Partial Enclosure

  • Maximum Noise Reduction: 6-15 decibels
  • Advantages: Very good noise reduction
  • Concerns: May have to incorporate view windows for visibility and/or sliding panels for access.
  • What Size? At a minimum, 8′ high. Typically they should be double the height of the noise source.
  • “BSC” or “BBC” sound absorption/noise barrier composites

Build a Complete Enclosure

Build a Complete Enclosure

  • Noise Reduction: Up to 20-30 decibels
  • Advantages: Maximum noise reduction
  • Concerns: May have to incorporate view windows for visibility and/or sliding panels for access as well as ventilation baffle(s) for air flow.
  • “BSC” or “BBC” sound absorption/noise barrier composites.
