The science behind tailored industrial noise control solutions for your project

7 key considerations for addressing noise pollution for your project

When you’re managing noise on a job site, it’s important to understand the science behind industrial noise control and how to apply it effectively. Whether you’re working on the floor, coordinating with architects, or managing the project, ensuring noise is properly controlled requires a strategic approach that’s guided both by sound acoustic principles and Australian Standards.

At Flexshield, we understand that every noise problem is unique. That’s why we offer a range of industrial noise control solutions, including Sonic Access acoustic doors, Sonic Series acoustic louvres, and Sonic Acoustic enclosures, designed to address the specific needs of your site.

Let’s dive into the process behind choosing the right solution for your project, with a focus on compliance with Australian Standards and creating practical applications. Here are the seven steps to incorporate.

1) Identifying the noise source

The first step in addressing industrial noise is identifying its source. Industrial machinery, equipment, and processes often create high sound pressure levels (SPL), which vary greatly depending on the noise generated. Noise is measured in decibels (dB), and understanding the SPL is essential to determine the necessary control measures.

Flexshield solution: Sonic Acoustic enclosures are ideal for machinery or areas that need to be fully enclosed to reduce noise. These enclosures are designed to fully contain machinery, preventing noise from spilling into the surrounding areas. They can be tailored to meet specific noise reduction requirements and ensure that your site complies with Australian noise regulations.

2) Frequency analysis

Industrial noise is not just about loud sounds; it also spans a wide range of frequencies. That’s why understanding the frequency profile of the noise is critical to selecting the right materials and solutions. High-frequency noise (such as fans and motors) requires different treatments compared to low-frequency sounds (like machinery rumbles).

Flexshield solution: Sonic Series acoustic louvres can help control mid- to high-frequency noise. These louvres reduce sound transmission and allow for ventilation, making them suitable for areas where airflow is important without compromising noise control.

3) Sound propagation and acoustic design

Once you’ve identified the source and measured the noise, understanding how sound propagates through a space is crucial. Noise can be absorbed, reflected, transmitted, or diffused, depending on the materials used in the environment. This is where acoustics come into play, and it’s essential to consider both internal and external noise propagation.

Flexshield solution: For spaces requiring access while controlling sound, Sonic Access acoustic doors are the perfect fit. These doors are designed to provide soundproofing without sacrificing ease of access for maintenance or operations. Whether it’s a noisy machinery room or a wall opening that needs noise containment, these doors help prevent sound leakage.

4) Australian noise standards and compliance

In Australia, noise control is not just about comfort – it’s about legal compliance. Australian Standards, such as AS 1055 and AS/NZS 1269, set limits on noise exposure, both within the workplace and in external environments. Compliance is critical to ensuring the health and safety of workers, as well as avoiding penalties for exceeding acceptable noise levels.

Flexshield solution: Designed with Australian Standards in mind, Sonic Acoustic Enclosures and Sonic Access Acoustic Doors are tested to meet the noise control requirements specified in AS 1055 for environmental noise. Additionally, our products help businesses comply with AS/NZS 1269, which covers acceptable workplace noise exposure.

5) Room acoustics and reverberation

In large, open spaces or areas with hard surfaces, sound can bounce around, increasing the overall noise level. This reverberation can amplify noise, making it more difficult to work in or manage. The reverberation time (RT60) measures how long sound lingers in a space after the source stops. The longer the reverberation, the louder and more uncomfortable the space becomes.

Flexshield solution: To tackle reverberation, Sonic Acoustic Enclosures can be fitted with sound-absorbing panels, creating a controlled environment that reduces the echo and absorbs the excess noise. In combination with other sound-absorbing materials, these enclosures ensure that sound is effectively managed within the space.

6) Material selection and practical solutions

Once the noise level and characteristics are understood, selecting the right materials is key. Sonic Series acoustic louvres are perfect for outdoor areas that require both sound control and airflow. For highly controlled internal environments, Sonic Acoustic Doors and Sonic Acoustic Enclosures can block sound transmission and maintain operational efficiency.

Flexshield solution: Flexshield’s range of products, including Sonic Acoustic Enclosures and Sonic Series acoustic louvres, are designed to work together or independently to address a wide range of industrial noise challenges. Whether you need to create a completely soundproof area or manage external noise without sacrificing ventilation, Flexshield has the solution.

7) Cost-effectiveness and long-term viability

Choosing the right noise control solution also involves considering the long-term impact on your project budget. While it’s tempting to focus solely on upfront costs, it’s crucial to weigh the long-term benefits of noise control. The best solutions not only reduce noise effectively but are also durable, easy to maintain, and comply with relevant standards.

Flexshield solution: Flexshield’s industrial noise control solutions are engineered for durability and long-term effectiveness, ensuring compliance with Australian noise regulations while offering a high return on investment. From Sonic Acoustic Doors to Sonic Acoustic Enclosures, our solutions are built to last and perform, keeping your site safe and compliant year after year.
