If you live near a busy road, have noisy neighbours, or simply want a bit more peace in your backyard, you’ve probably wondered: can a fence really reduce noise? The short answer is yes — but it depends on the design, materials, and placement of the fence.
At Hobart Fencing and Gates, we’ve helped many Tasmanian homeowners choose the right fencing solutions to reduce sound and improve outdoor comfort. In this post, we’ll explore how noise-reducing fences work, which types are most effective, and whether they’re the right solution for your property.
How Sound Travels – And How Fences Can Block It
Sound moves in waves, and like light, it travels through air and around objects. A regular fence might deflect or absorb some sound, but not all materials are created equal when it comes to blocking noise.
To be truly effective, a noise-reducing fence must:
- Be tall enough to block direct sound paths
- Be made of dense, solid materials
- Have minimal gaps or openings
The goal is to reflect or absorb sound waves before they reach your outdoor living spaces or home interior.
What Makes a Fence “Noise-Reducing”?
Here are the key characteristics of an effective acoustic fence:
- Height
The taller the fence, the better. Aim for at least 1.8 to 2.4 metres, as sound waves can easily travel over short barriers. - Material Density
Heavier materials (like timber, Colorbond steel, or masonry) are much better at blocking noise than lightweight options like chain link or slatted panels. - No Gaps
Sound can easily pass through cracks. A true noise-reducing fence should be completely solid, with tight joins and no spaces underneath. - Continuous Structure
For best results, the fence should run without interruption along the sound source side. Gaps for gates or garden beds reduce effectiveness.
Best Fencing Materials for Noise Reduction
- Colorbond Fencing
Colorbond is one of the most popular fencing choices in Tasmania – and with good reason. Its steel panels are solid, durable, and tightly sealed, which helps reduce noise from traffic or nearby properties. - Timber Fencing
Solid timber fences (such as lapped and capped paling) also offer excellent sound insulation, particularly when double-sided or with added backing boards. - Masonry or Brick Walls
While more expensive, brick or rendered concrete walls are the most effective at blocking sound due to their density. - Composite Acoustic Fencing
These modern solutions use special noise-dampening cores and offer excellent soundproofing performance, though availability can be more limited.
What About Acoustic Panels or Barriers?
Some fences can be retrofitted with acoustic panels, soundproofing mats, or mass-loaded vinyl for extra noise control. This can be a smart option if replacing your whole fence isn’t practical.
Tips for Improving Fence Sound Insulation
- Add a hedge or shrubs in front of the fence — vegetation helps absorb sound.
- Include overlapping or double panels to prevent sound leakage.
- Consider landscape contours — placing the fence closer to the noise source improves effectiveness.
- Don’t forget gates — they should be built solid and sealed like the rest of the fence.
Do Noise-Reducing Fences Really Work?
Yes — if designed and installed properly. While no fence can block 100% of outdoor noise, a well-constructed noise-reducing fence can significantly dampen unwanted sound and make your home feel more private, peaceful, and enjoyable.
The key is choosing the right material, building it at the right height, and avoiding gaps.
