Noise management is an important factor in planning a construction project. Noise walls are the most effective method of mitigating noise pollution in surrounding environments. But with so many options available, how do you choose the best noise wall for your project? In this article, we’ll explore the factors you should consider when selecting a noise wall and contacting a specialist to assist you in noise wall construction and installation.
The purpose of your noise wall
Before diving into the specifics, it’s essential to understand the primary purpose of the noise wall you require. These structures are designed to reduce the noise levels produced by industrial spaces such as highways, railways and industrial sites, and commercial spaces including malls, drive-through restaurants and petrol stations. More recently, noise walls have also become a vital element in battery energy storage systems.
The correct noise wall can effectively create a more peaceful environment for nearby communities. To ensure that you’re making the right decision, the best approach is to seek the assistance of a professional. Before you do, here are a few factors to consider and how they affect your noise wall choice.
Height and length of your noise wall
The height and length of the noise wall will affect both its acoustic performance and its visual impact. Taller walls may block more sound, however you may need to consider utilising perspex inserts so that the wall doesn’t block the sun in surrounding areas. If you are looking for a shorter wall, lightweight noise walls may be what you’re looking for, especially if you are looking for something customisable.
Selecting the correct material
The material you choose for your noise wall will significantly influence its acoustic performance, durability, maintenance needs, and environmental impact. Here are some of the most common materials used for noise walls –
Concrete
Concrete is a popular choice in noise wall construction projects, due to its durability and excellent sound-blocking capabilities. Concrete noise walls combine aesthetic appeal with exceptional functional resilience and are engineered to meet rigorous standards for noise reduction, structural integrity, and environmental considerations. They are also designed to withstand impact, serving as a robust barrier against both sound and physical collisions. The high-strength precast concrete panels ensure superior durability and structural performance, offering an efficient and cost-effective solution without compromising on quality.
Steel
Steel noise walls are renowned for their superior noise mitigation properties, crafted from quality non-combustible materials that adhere to Australia’s highest compliance standards.
There are two types of steel noise walls available –
- Corten steel, which has a naturally weathering rust finish that blends seamlessly with outdoor landscapes, while effectively mitigating noise
- Galvanised steel is available in a range of colours, which offers a more modern aesthetic, as well as significant noise mitigation properties.
Recycled rubber
Recycled Noise Walls offer an innovative approach to sustainable sound management, combining eco-friendliness with superior noise reduction capabilities. Made from high-quality recycled rubber, these barriers are perfect for a range of environments, from highways to residential areas. They provide excellent noise mitigation properties and can be customised using decorative turf and even logo application.
Perspex
Customisable perspex inserts are ideal for projects where overshadowing is a concern. These opaque inserts allow more natural sunlight to brighten surrounding areas, while enhancing the aesthetic appeal of your noise wall. Perspex inserts are available in a wide range of colours, and can be seamlessly integrated into the existing wall design.
Types of noise walls
Lightweight noise walls
Lightweight noise walls offer an innovative solution for those looking to achieve effective noise reduction without the constraints of traditional barriers. Designed for versatility and performance, these walls meet all compliance standards and are ideal for various environments, including urban landscapes and residential areas. With a range of post options available, our lightweight noise walls can be seamlessly integrated into any project, ensuring they are perfectly tailored to the specific needs of your space.
Commercial noise walls
Commercial noise walls are the more heavy-duty option. They offer exceptional noise mitigation and impact resistance, standing strong against environmental factors while maintaining their structural integrity and appearance over time.
Renowned for their durability and longevity, these walls are built to last for decades with minimal maintenance. Their inherent fire resistance adds an extra layer of safety, ensuring they withstand high temperatures and prevent the spread of fire. Commercial noise walls are most often used to mitigate highway noise and to protect surrounding suburbs from noise caused by general noise, traffic and construction.
Budget Considerations
Finally, your budget will play a significant role in determining which noise wall is best for your project. While it’s tempting to opt for the most cost-effective solution, it’s crucial to consider the long-term costs associated with installation and maintenance. Here’s how to balance cost with performance:
Initial costs vs. long-term savings
Concrete noise walls might have higher upfront costs, but due to their durability and low maintenance needs, they can offer significant savings over time.
Cost-effective customisation
Modular noise walls can be a cost-effective solution that allows for customisation in height, length, and design, making them adaptable to various project needs without breaking the bank.
