Tips for Controlling Noise in a Factory Setting

Factories are designed with efficiency and safety in mind. One of the biggest safety hazards within a manufacturing setting involves noise levels. High levels of noise can lead to a variety of health issues for employees, so this problem requires the services of an acoustical consultant. An acoustical consultant will inspect a factory or any type of manufacturing setting and offer recommendations that are required. Many of the noise regulations are mandated by law. This means that it can be beneficial for you to try cost effective methods for lessening noise levels to the satisfaction of an acoustical consultant.


It is possible to lessen the amount of noise by making sure that all ductwork is fitted with silencers. There is quite a bit of noise in a factory setting that is known as airborne noise that comes from ductwork. This can be minimised by lining the last bend in the ductwork with a type of material known to absorb sound. This can be anything from rockwool to fiberglass material. This duct vibration and sound production will be lessened through using lining on the bends within the ductwork.

Drop Fan Speed

One of the main culprits of noise within a factory can be linked to fan use. Fans have the ability to produce high amounts of noise, especially if they are on the highest setting. Lowering sound production within a factory can be made more attainable by lowering fan speed by one setting. Changing the control systems or re-setting the dampers can allow the fans to produce much less noise.

Replace Nozzles

Changing the type of nozzles being used in manufacturing equipment including hoses injectors can help to reduce noise levels.  Efficient nozzles are different and are not made from copper pipe outlets. Not only are noise levels reduced by more efficient nozzles, but they also require the use of less compressed air, which is the main culprit of the noise within this setting.

Vibration Isolation Pads

It is possible to reduce the transmission of vibration and sound by using vibration isolation pads. Securing these pads properly is the key to getting the most vibration reduction. It is common for the bolt to short circuit the pad, but this can be avoided by simply placing additional vibration isolation pads underneath the bolt heads. The bolt heads are designed to keep the pads in place, but the vibration pads need to be properly secured. There are different types of rubber that can be used to cut back in noise production most effectively depending on the type of factory where they are being installed.
