Worksites tend to be filled with constant noise from tools and machinery. Work-related hearing loss is a real threat for many who spend the majority of their working lives on-site. While noise often means things are getting done, there is a downside to it. Hazardous noise can affect a worker’s physical and mental wellbeing including hearing loss, stress, and lower productivity. So to help you protect your hearing, here are a few helpful tips to manage noise. 

Understand noise and it’s path

Understanding what makes noise on-site, how it impacts people and different areas on site is critical. Ask yourself and your workers: 

• Where does most of the noise come from? 
• What tools or machinery are the loudest? 
• How does noise travel around the site?

Once you understand the answers to the above, you can start putting plans and checks in place to monitor noise on-site. 

Be sure to review the plan throughout the project, as different stages will create varying levels of noise. 

Eliminate or reduce

The easiest way to decrease the effect of excessive noise on your site is to eliminate the source of noise completely. But, chances are this isn’t possible on a busy site. 

The next best thing is to reduce noise. 

A couple of easy ways to do this include: 

• Using less powerful tools 
• Wear correct hearing protection where possible
• Keep noisy machinery or work stations away from walls or corners – really anywhere noise can bounce off and echo throughout site

Isolation

Isolation involves creating a dedicated space for ‘noisy work’. This could be an enclosed room or area of site where all noisy work and machinery is used. This helps manage the noise by blocking the path of noise and reducing the levels that reach your team.

Engineering

Having a good understanding of how machinery and tools operate can help modify processes to reduce noise at the source. Engineering controls can include choosing attachments or parts that are noise reducing, or changing the way machinery and tools are used.

Acoustic enclosures

Perfect for when you are running a large generator or a dedicated workspace, acoustic enclosures help to trap the noise within its barriers.

Setting up an acoustic enclosure that has 2 or 3 barriers/ walls can reduce noise.

What makes a quality acoustic enclosure: 

• Sealed windows and doors – make sure everything is closed or the noise escapes 
• Double or triple glazed windows and walls 
• Materials that are compact, dense and heavy

Vibrations

With noise comes vibrations. These vibrations can be just as harmful as the noise itself. 

Here are a few strategies to help decrease vibrations when using machines or power tools: 

• Heavy surfaces vibrate less and radiate less noise. So if you can, perform all work with power tools on heavy surfaces, such as concrete.
• If you can, work on benches/ surfaces that aren’t solid – holes allow noise to escape and not bounce off the surface.
• Place machinery or generators in an area of site where they are not trapped by walls unless they are made of noise-cancelling/ absorbing materials.

It’s not possible to escape noise on-site, however we can manage noise and put steps in place to help reduce the effect that it  has on us while we’re working.
