What Type of Fencing Is Best for Noise Reduction? (Australian Guide)

Looking for a way to block out traffic noise or loud neighbours in Melbourne? Acoustic fencing is one of the most effective solutions to reduce unwanted noise around your property. This guide explains which fencing materials work best for noise reduction, how they perform in Melbourne’s climate, and what local homeowners should know before installation.

Quick Answer

What fencing is best for noise reduction in Melbourne?

The best fencing options for noise reduction in Melbourne are:

• Masonry fences (e.g. concrete or brick walls)

• Modular acoustic panels

• Lapped and capped timber fencing with acoustic insulation

• Upgraded Colorbond fencing with acoustic foam or mass-loaded vinyl

For maximum noise blocking, the fence should be at least 2 metres tall, have no gaps, and be made from dense, solid materials.

Why Is Noise-Reducing Fencing Important in Melbourne?

Melbourne is known for its vibrant urban lifestyle—but with that comes road noise, construction, railway lines, and dense housing. Whether you live near CityLink, a tram line, or in a bustling suburb like Footscray, Brunswick, or Richmond, noise pollution can disrupt your peace.

Installing the right type of acoustic fence can:

• Cut down road and train noise

• Improve your home’s privacy and resale value

• Make your backyard more enjoyable

How Does Acoustic Fencing Reduce Noise?

Effective noise-reduction fences work through two main principles:

1. Sound Deflection

The fence acts as a solid barrier, reflecting sound waves away from your property.

2. Sound Absorption

Some materials absorb sound waves, reducing their energy and transmission.

The most effective sound-reducing fences combine both principles. In general:

• Heavier = better noise blockage

• Taller = wider shadow zone (the quiet area behind the fence)

• Airtight = prevents sound leakage

For Melbourne homes, fences must withstand both noise and weather (e.g. summer heat, coastal winds, winter moisture). That’s why choosing the right material matters.

Now let’s explore which fencing materials and designs deliver the best noise insulation.

Top 5 Types of Fencing for Noise Reduction in Australia

1. Timber Fencing (with Acoustic Panels)

Best for: Residential backyards in suburbs like Coburg, Reservoir, or Glen Waverley

Timber is a popular choice for its natural appearance and affordability, but standard paling fences are not great for noise control due to gaps between boards. However, acoustic timber fencing is a game-changer.

Best Options:

• Lapped and capped timber fencing

• Acoustic-rated timber panels (e.g., modular sound barriers)

Benefits:

• Affordable

• Readily available across Australia

• Can be modified with mass-loaded vinyl or acoustic blankets

Limitations:

• Requires regular maintenance

• Not as durable as concrete or metal

Noise Reduction Rating: ★★★☆☆ (3–4 STC with acoustic upgrade)

2. Modular Acoustic Barriers (Composite or Polyvinyl Materials)

Best for: Urban infill areas, schools, businesses, or homes near train lines

Pre-engineered acoustic fencing panels are designed specifically for sound reduction. Brands like ModularWalls, Gramline, and Echo Barrier are popular in Australian markets.

Key Features:

• No gaps between panels

• Dense core materials (e.g., recycled plastic, composite, or sound-rated foam)

• Stylish modern finishes

Benefits:

• Engineered for acoustic performance

• Low maintenance

• Easy to install and customise

• Resistant to rot, insects, and moisture

Limitations:

• Higher upfront cost

• May need council approval if over height limits

Noise Reduction Rating: ★★★★☆ to ★★★★★ (up to 35+ STC)

3. Masonry Fencing (Concrete, Brick, or Stone Walls)

Best for: Homes on busy roads like Hoddle Street or Bell Street

Masonry fences offer exceptional noise reduction due to their sheer density and airtightness. They’re ideal for homes on main roads, near train lines, or industrial zones.

Options:

• Double-skin brick walls

• Precast concrete panels

• Stone or block walls

Benefits:

• Superior noise deflection

• Long lifespan

• Adds property value and street appeal

Limitations:

• High installation cost

• Labour-intensive construction

• Limited flexibility if you need modifications later

Noise Reduction Rating: ★★★★★ (35–50 STC)

4. Colorbond Fencing (with Modifications)

Common across Melbourne’s west and southeast suburbs

Colorbond steel fencing is ubiquitous in Australian backyards, prized for its durability and clean look. However, standard Colorbond panels provide moderate acoustic performance.

Noise-Reducing Enhancements:

• Install with no gaps at the bottom

• Use acoustic foam inserts

• Pair with hedging or acoustic plants

Benefits:

• Resistant to weather and pests

• Low maintenance

• Widely available

Limitations:

• Requires add-ons to improve soundproofing

• Metal reflects sound more than it absorbs

Noise Reduction Rating: ★★☆☆☆ to ★★★☆☆ (18–25 STC with upgrades)

5. Earth Berms and Living Sound Barriers

Best for: Larger Melbourne blocks or eco-friendly designs

For large properties or eco-conscious homeowners, earth mounds (berms) or thick vegetation barriers can work in combination with fencing.

Example Setup:

• Berm with dense shrubs + acoustic fence behind

Benefits:

• Natural aesthetics

• Doubles as windbreak and wildlife habitat

• Effective when space permits

Limitations:

• Requires significant land

• Long time to mature if using plants

• Plants alone don’t reduce high-frequency noise well

Noise Reduction Rating: ★★★☆☆ (when combined with fencing)

Factors to Consider When Choosing a Noise-Reducing Fence

1. Type and Source of Noise

• Low-frequency (e.g. trucks, bass music): masonry or acoustic composite is best

• High-frequency (e.g. voices, birds): dense timber or composite works well

2. Height and Length

• Minimum 2 metres high for effective noise shielding

• Longer fences protect a wider shadow zone

• Check local council rules (heights over 2.1m may need permits)

3. Spacing from Noise Source

• Closer to the noise source = better reduction

• If that’s not possible, place fence as close as possible to your property line

4. Sealing and Installation

• Ensure no gaps at the base or between panels

• Overlap boards if using timber

• Consider acoustic caulking or foam sealants

5. Budget and Aesthetics

• Brick and modular fences are more expensive but effective

• Colorbond and timber offer flexibility with custom styling and lower cost

Additional Tips to Maximise Fence Noise Reduction

Combine Fencing with Landscaping

• Use hedges or shrubs as a second barrier

• Add climbing plants like jasmine on the fence for extra sound diffusion

Install Mass-Loaded Vinyl (MLV)

• Attaches behind timber or Colorbond fences

• Boosts STC rating by up to 10 points

Use a Double-Layered Fence System

• Two fences with a gap in between create a sound buffer zone

• Fill the gap with acoustic insulation or plants

Council Regulations and Permits in Australia

Before installing a tall or solid acoustic fence, check with your local council. Regulations vary by state, but generally:

• Fences above 2 metres require approval

• Shared boundary fences may need neighbour consent

• Heritage areas may have style restrictions

Contact your local council or consult a licensed fencing contractor for guidance.

Expert Tip: Combine Fence with Landscaping

For Melbourne gardens, combine your acoustic fence with:

• Climbers (e.g., Jasmine, Star jasmine)

• Dense shrubs (e.g., Viburnum, Camellia)

• Native hedges (e.g., Acacia cognata)

This not only improves sound absorption but enhances your home’s kerb appeal.

Frequently Asked Questions (FAQs)

Q: Can any fence reduce noise?
A: Not effectively. Only solid, airtight, and heavy fences significantly reduce sound transmission. Standard paling or slatted fences let noise through.

Q: What is the most effective noise-reducing fence in Australia?
A: Brick or concrete walls are best, followed by engineered acoustic composite panels designed for sound control.

Q: How tall should a fence be to reduce road noise?
A: Ideally, at least 2 metres high. Higher is better, as long as local council regulations permit it.

Q: Is Colorbond good for blocking noise?
A: By itself, it offers moderate performance. But with acoustic backing or insulation inserts, Colorbond can become more effective.

Q: Do plants help with noise reduction?
A: Yes, but only when used with a solid fence. Thick shrubs or hedges alone do little to block low-frequency noise like traffic.
