What is an Acoustic Fence?
An acoustic fence is a specially designed barrier that reduces noise pollution by blocking or absorbing sound waves. Acoustic fences are commonly used anywhere that noise can be reduced, so in residential areas, along roads, around commercial or industrial sites, schools, places of worship and near railways and transport infrastructure to create a quieter environment.
How Does an Acoustic Fence Work?
Acoustic fences work by either reflecting or absorbing sound waves, depending on their design and materials. The effectiveness of an acoustic fence depends on factors such as its height, density, and construction.
Reflective vs Absorptive Acoustic Fencing
There are two main types of acoustic fences: reflective and absorptive.
Reflective Acoustic Fences
Reflective fences work by bouncing sound waves away from the source, typically back towards the direction they came from.
These fences are made from dense, solid materials with no gaps such as thick timber, metal, concrete or even Perspex. While they effectively block noise, they can sometimes cause sound to reflect into unintended areas, which may not always be ideal in urban settings.
Absorptive Acoustic Fences
Absorptive fences are specifically designed to capture and dissipate sound energy rather than reflecting it. Constructed from porous materials or specialised acoustic panels, they effectively absorb sound waves, significantly reducing overall noise levels. These fences are commonly used in environments where containing noise is essential, such as railway depots, industrial sites, retail and supermarket loading bays, as well as HVAC or power generation compounds. By preventing sound reflection, they play a crucial role in effective noise control.
Where Are Acoustic Fences Used?
Acoustic fencing is commonly installed in:
- Residential areas – to reduce traffic noise and create peaceful gardens.
- Roadside locations – to limit vehicle noise for nearby homes and businesses.
- Railways – to minimise train noise in urban and rural communities.
- Industrial and commercial sites – to contain machinery noise.
- Schools and playgrounds – to shield children from traffic noise.
Choosing the Right Acoustic Fence
When selecting an acoustic fence, consider:
- Material and density - Heavier materials provide better noise reduction.
- Height - A taller fence blocks more noise.
- Absorptive vs reflective - Choose based on your specific noise control needs.
- Aesthetic appeal - Many acoustic fences are designed to blend into their surroundings.
- Quality and guarantee - Acoustic fences are slightly more expensive than standard fences, so it is important to invest in durability. The last thing you want is to replace them after just five years. To ensure longevity, choose products with long guarantees and high-quality materials.
Acoustic Fence Installation
Acoustic fences are typically installed differently from standard fences. They may require specialised posts, overlapping boards, or specific construction methods to meet soundproofing requirements. Additionally, installation may need to adhere to specifications set by a sound engineer.Are There Any Additional Benefits to Acoustic Fencing?
Beyond noise reduction, acoustic fences offer several other advantages due to their size and structure. They enhance privacy by forming a solid barrier and if it is a reflective fence designed with smooth surfaces and no footholds or handholds, this can provide very good security.
Additionally, they can help reduce light pollution, provide protection from strong winds and harsh weather, and contribute to a more comfortable outdoor environment. Many acoustic fences also add aesthetic appeal, increase property value, and, when made from sustainable materials, offer an eco-friendly fencing solution.
Are Acoustic Fences Worth the Extra Investment?
Acoustic fences provide a proven and effective solution for managing noise pollution in various environments. Whether using a reflective fence to block noise or an absorptive one to neutralise it, these barriers help create quieter, more comfortable spaces.
