Noise control is not a nice-to-have – it’s a necessity

Whether your industrial site is a mine, processing facility, or infrastructure project, its sound has a way of pushing its way into places it does not belong. And when left unchecked, industrial noise becomes more than a nuisance. It becomes a problem for productivity, safety, and compliance.

That’s why at AcousTech, we dedicate our lives to the science of silence. Through decades of research, testing, and fieldwork, we have identified three foundational methods for managing industrial sound. They are:

• Attenuation
• Absorption, and
• Blocking.

And yes, they each do something very different.

Let’s break down the mechanics of how noise moves through your worksite, and how our industrial soundproofing solutions can outsmart it.

Attenuation stops sound from travelling too far

Just like heat, sound travels. Attenuation is the process of interrupting that movement.

In an industrial setting, attenuation works by reducing the intensity of sound as it leaves its source. The earlier you catch it, the better your control.

One good example of attenuation is our Sonic Series acoustic louvre. These louvres allow airflow and ventilation without letting sound slip through. Unlike standard metal louvres, Sonic Series acoustic louvres are precision-engineered with absorptive linings and geometric design features that actively reduce transmission loss.

For large-scale infrastructure or energy projects, acoustic louvres create a quieter perimeter, helping you meet environmental noise targets without compromising air movement.

Absorption softens echo and reverberation inside a space

When noise hits hard surfaces, it reflects. This causes echoes, higher decibel levels, and a chaotic working environment. Sound absorption involves capturing this excess energy and reducing the internal volume.

That’s where Sonic acoustic enclosures and Sonic System acoustic modular panels shine. By surrounding noisy machinery or enclosing high-volume zones, these solutions absorb stray sound waves and keep them from bouncing around the space.

From CNC shops to mobile mining equipment, our industrial soundproofing solutions adapt to your layout, reducing reverberation while maintaining access and flexibility. Absorption improves communication on site and gives your team a better environment to focus in.

Blocking keeps sound contained to where it belongs

Some noise can be allowed to ‘breathe’. Some needs to be completely shut off. Blocking is the act of separating sound sources from sensitive areas, such as a site office, neighbouring property, or another process line.

Sonic System modular acoustic panels can be configured to form freestanding barriers or permanent partition walls. For full enclosure builds, Sonic Access acoustic doors complete the acoustic solution. Purpose-designed for high-noise industrial zones, these doors maintain acoustic integrity while allowing safe, regular access for maintenance and operations.

Whether you are isolating a compressor room, managing breakout noise from plant rooms, or preventing transfer into noise-sensitive neighbouring areas, blocking is about drawing a firm acoustic line between loud and quiet.

Every site is different, but the goal for noise control remains the same

Reducing exposure to harmful noise, improving acoustic comfort, and achieving EPA compliance requires more than just products. It requires a strategy that accounts for your processes, your equipment, and your people.

At AcousTech, we’re more than acoustic engineers. We are scientific thinkers and systems designers, who apply our knowledge to the real conditions of your site for the ideal industrial soundproofing solutions. Powered by Flexshield and backed by years of site testing across Australia’s toughest sectors, we know what works and what doesn’t.
