WAYS TO QUIET A NOISY MACHINE

There are a few different ways that you can go about quieting a noisy machine. One way is to make sure that all of the parts are properly secured. If any of the parts are loose, they will vibrate and cause noise. Another way to quiet a machine is to add soundproofing material to it. This can be done by adding special pads or foam to the areas that are prone to vibration. Finally, you can also try using a sound dampening compound on the machine. This will help to absorb some of the noise and make it less noticeable. By following these tips, you should be able to significantly reduce the noise level of your machine.

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.
• Quilted Fiberglass Sound Absorption Products…or Polywrap Baffles, depending upon specifics of application.

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.
• Treat the wall behind the machine with about twice the square footage of the “shadow” of the machine on the wall.

Build a Soundproofing 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.
• Size? Minimum of 8′ high. Typically they should be double the height of the noise source. • Sound absorption/noise barrier composites.

Build a Complete Soundproofing 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.
• Sound absorption/noise barrier composites
