How do you control industrial noise?

Factories manufacture all kinds of different things, but there’s one by-product that nearly all of them have in common: noise.

Of course, sound levels vary depending on the industry—some are inherently noisier than others. This can be a serious concern for the health and safety of workers, as well as nearby communities.

What are the sources of this noise, and how can it be prevented from becoming a major problem? In this article, we’ll outline some of the key contributors and explain how IAC Acoustics Australia is leading the way in reducing its impact.

What are the main sources of factory noise?

The soundtrack in a factory is often a complex mix of noises emanating from a range of sources. These include:

Heavy industrial equipment: this might include chillers, turbines, conveyors, motors, agitators, boilers, pumps, fans, compressors, furnaces, engines, and blowers. These machines are fundamental to industrial operations but can produce significant noise levels, from the low hum of a motor to the loud bangs of heavy machinery.

Industrial processes: Each sector’s specific processes can significantly contribute to noise levels. For instance, the automotive industry might deal with the noise of large assembly lines, while chemical processing might involve periodic high-decibel noise from reactions or machinery.

Compressed air systems: Often used in manufacturing, compressed air systems, including pumps and compressors, are another notable source of noise, particularly when they are old, poorly maintained, or not properly insulated.

How do you control industrial noise?

Having identified the sources of noise, it’s time to look at some of the most effective solutions to reduce their impact. Here’s how IAC Acoustics Australia addresses these challenges:

Acoustic enclosures

IAC Acoustics designs acoustic enclosures to specifically target and reduce noise from machinery like pumps, fans, or entire areas such as bottling plants. Made with materials like mass-loaded vinyl or metal panels, these enclosures effectively contain noise at the source. They’re built for durability and designed to allow easy access to the machinery for maintenance. This solution is essential in environments where noise reduction is crucial for compliance with health and safety and worker comfort.

Acoustic barriers

These barriers are crucial in preventing sound from travelling to sensitive areas. They are used both inside the factory and in the surrounding areas, and do an excellent job at reducing noise pollution. These barriers are also designed to blend with the environment, offering an effective solution without compromising aesthetics.

Sound absorptive panels

IAC Acoustics’ trademarked Varitone sound absorption system uses wall and ceiling panels to control echo and reverberation, which helps significantly lower overall noise levels. This reduction in constant background noise means less strain on workers’ hearing over the course of a day, leading to reduced auditory fatigue. In a calmer auditory environment, workers can communicate more easily and concentrate better, which boosts overall productivity and comfort in the workspace.

Creating a better industrial environment

In the industrial world, effective noise management isn’t just about adhering to health and safety regulations; it’s about creating a better work environment and being a responsible member of the local community. 

With over 70 years of experience, IAC Acoustics has been instrumental in helping our industrial partners improve work-life quality and establish quieter, more focused workplaces.
