5 Ways to Quiet a Noisy Machine

Published On September 28, 2018 | By Carolyn Guertin | Technology

Anyone who has been near an operational machine or other industrial equipment is obviously familiar with the vibrations generated. If not addressed, these vibrations may affect the overall performance of the machinery; the vibrations tend to loosen and damage the machine parts. Machines that run without anti vibration mounts have a shorter life span and also cause inconvenience to the worker.

Usually, as the equipment vibrates it also produces noise. The noise can be quite distractive and uncomfortable especially for people working in the room. The anti vibration mounts are designed in such a way that they significantly reduce noise pollution and withstand adverse conditions. Low carbon steel is used to make the mounts because it does not rust.

Factors to Consider When Choosing an Anti Vibration Mount

Some of the things that one should bear in mind when they’re looking for anti vibration mounts are:

  • The intensity of the vibrations
  • The size of the mounts
  • Their load bearing capacity
  • The deflection characteristics

Factors Affecting Vibration Measurements

Basically, vibration is the periodic displacement of an object around its central static position. For a vibration to be measured, different parameters are put into consideration. There are:

  • Frequency
  • Acceleration
  • Velocity
  • Displacement

How to Quiet a Noisy Machine

  • Using Anti Vibration Mounts

One of the most obvious ways of quieting down a noisy machine is by installing anti vibration mounts. These are either made from materials such as rubber or springs and they absorb the vibrations that are produced by machines. Not only do the mounts minimize the negative effects associated with these vibrations by they also help the machinery to run more smoothly.

Anti vibration mounts are made of heavy-duty material to provide maximum isolation. They can withstand different types of load stress that they are subjected to. Their shape depends a lot on the load­deflection needs.

Due to the pressure placed on them, the anti vibration mounts are bound to wear and tear after a period of time.

It’s advisable that you assess the status of the mounts regularly to see whether or not they should be changed. If they’re not changed regularly, the machinery will start producing vibrations just as it used to before the anti vibration mounts were installed in the first place.

  • Treat The Room

Treat the whole room using quilted fiberglass sound absorption products. The noise will be decreased by about 30%; this is approximately 6-9 decibels

  • Treat The Wall Behind The Noise

The wall behind the noisy machine is treated with about twice the square footage of the noise shadow. The noise will be reduced by approximately 4-6 decibels

  • Build A Partial Enclosure

Build a barrier that is double the height of the noise source. Include sound absorption composites into the wall.

The noise will be reduced by approximately 6-15 decibels

  • Build A Complete Noise Enclosure

Just like in no.4 above, a wall is built and sound absorption composites are included. However, make sure to incorporate glass to allow for visibility as well as ventilation baffles for air flow and sliding panels for access.
