There are so many ways in which various industrial activities can create noise that can in one way or another present a problem, especially to those working in or living near the vicinity. For every problem these days there is a workable solution, available at varying cost in terms of purchase and installation. To run through all of the potential industrial noise control solutions available would take a considerable amount of reading, so let’s look at some of the most popular and effective ways of controlling industrial noise, starting with those that tackle specific pieces of machinery and their noisy parts. Let’s call these options microscale noise control.

Microscale noise control examples:

Machines in general

In order to quieten down noisy machines it is important to think how they can be made more efficient as well as quieter. This is often done via the installation of chains and timing belts, installing modifications to reduce noise, using electric motors, replacing old and partially faulty machinery and by using hydraulic power packs. Sometimes it is also possible to modify existing safety guards for machinery to maximise their potential for acoustic control.

Fantastic fans

Often some of the noisiest elements of an industrial operation are the various fans. These can be adapted for minimum noise and maximum efficiency. There is the option for aerodynamic fan noise control systems to be installed and it is also an option to retro-fit fans with aerodynamic modifications which can yield less noise and greater efficiency.

Good vibrations

A lot of noise pollution is caused by vibration. There are damping options for vibration control, which can reduce the vibrational noise caused by guards, hoppers, tanks and conveyors. Vibration isolation pads can also be fitted to reduce the noise of motors and pumps.

In addition there are things you can do about the overall noise in certain rooms of industrial buildings. Let’s pup these options under the umbrella of macroscale noise control.

Macroscale noise control options:

Within the walls of any industrial operation there are not only rooms that generate substantially more noise than others, but there are rooms where it is important to keep noise levels down, such as offices and quiet eating areas. To do this there are some good options, but one of the best is to install acoustic doors.

Acoustic doors are specifically engineered to keep noise within a specific room and out of another. They are made with special steel and can be made to suit various specifications and noise levels. In addition you can get hinged or sliding acoustic doors, which is important as some industrial operations necessitate a specific choice.

In order to be able to offer respite areas for workers involved in noisy operations it is important to be able to offer noise havens. This is also imperative for any rooms where sensitive operations are carried out. Noise havens can be designed to further treat noise at its destination as opposed to its source. Such havens are designed to keep noise out and come with ventilation systems and often glazed viewing panels.
