Acoustic Sound Barriers and Fencing for Noise Reduction

External noise can be frustrating when it affects your home, garden, workplace or commercial site. Traffic, nearby roads, passers-by, plant equipment, service yards and neighbouring activity can all make outdoor and indoor spaces feel less comfortable.

Acoustic sound barriers and fencing can help reduce some external noise where the barrier is correctly positioned between the noise source and the area being protected. The result will depend on the site layout, noise source, barrier height, density and installation quality.

What Are Acoustic Sound Barriers?

Acoustic sound barriers are designed to reduce noise travelling from one outdoor area to another. They are usually installed along boundaries, around plant equipment, beside roads, near service areas or around commercial sites where noise needs to be managed.

Unlike standard garden fencing, acoustic barriers are designed with mass, density and continuity in mind. These details help the barrier interrupt the path of sound more effectively.

Where Acoustic Barriers Can Be Used

Acoustic fencing and barriers can be useful in a range of domestic, commercial and industrial settings.

Homes and gardens affected by road or neighbour noise
Boundaries close to busy roads or external noise sources
Plant rooms, external equipment and service yards
Schools, leisure sites and community buildings
Commercial yards, loading areas and industrial sites
Outdoor hospitality areas and venue boundaries

How Acoustic Barriers Reduce Noise

Acoustic barriers work by blocking or interrupting the direct path between the noise source and the receiver. For example, a barrier may sit between a road and a garden, or between a noisy item of equipment and a neighbouring property.

The barrier needs to be high enough, dense enough and continuous enough to be effective. If sound can easily travel over, around or through gaps in the barrier, the overall reduction may be limited.

Height and Position Matter

The height and position of an acoustic barrier are important. A barrier that is too low may have limited impact because sound can travel over the top. A barrier that is poorly positioned may fail to interrupt the main sound path.

Where possible, the barrier should be positioned close to the noise source or close to the area being protected, depending on the site layout and the practical restrictions of the space.

Avoid Gaps and Weak Points

Sound can pass through surprisingly small openings. Gaps between panels, spaces at the base, weak joints, openings around posts and poorly sealed edges can all reduce acoustic performance.

For this reason, acoustic barriers should be installed carefully, with attention given to continuity, sealing and ground contact where appropriate.

Acoustic Barriers for Road Noise

Road noise is one of the most common reasons people consider acoustic fencing. Cars, lorries, buses and motorbikes can all create noise that affects gardens, outdoor seating areas and rooms facing the road.

An acoustic barrier may help where the site layout allows the fence to interrupt the line of sight between the road and the affected area. However, road noise can also enter a property through windows, walls, doors, roofs and vents, so internal soundproofing may also need to be considered.

Acoustic Barriers for Plant and Machinery

External plant, machinery, pumps, extract systems, chillers and generators can create noise that affects nearby rooms or neighbouring properties.

In these cases, acoustic barriers may form part of a wider noise control approach. Depending on the equipment, acoustic enclosures, doors, wall treatment, sealing work or vibration control may also be needed.

Acoustic Barriers for Homes and Gardens

For homes, acoustic fencing may help make gardens and outdoor spaces more comfortable where noise is coming from a clear external source. It can also help reduce some noise movement between neighbouring outdoor areas.

Every property is different, so it is important to consider the height of the noise source, the position of nearby buildings, the slope of the land and whether sound can travel around the barrier.

Acoustic Barriers for Commercial Sites

Commercial and industrial sites may use acoustic barriers to help manage noise from service yards, loading bays, external equipment, delivery areas or boundaries close to neighbouring properties.

For these projects, the barrier specification should be chosen based on the source of the noise, the surrounding environment and the level of reduction required.

Sound Barriers vs Internal Soundproofing

Acoustic barriers are mainly used to reduce outdoor sound paths. Internal soundproofing is used when noise is entering, leaving or travelling through a building.

If traffic noise is entering through a bedroom window, for example, an external barrier may help in some layouts, but windows, seals, walls and ventilation routes may also need to be reviewed.

Soundproofing vs Sound Absorption

Soundproofing and sound absorption are different acoustic treatments. Soundproofing helps reduce sound passing from one space to another. Sound absorption helps control echo and reverberation within a space.

Acoustic barriers are a soundproofing measure because they are designed to reduce sound travelling between outdoor areas. If an indoor room feels echoey, sound absorption products may be more relevant.

Can Acoustic Barriers Remove All Outdoor Noise?

Acoustic barriers can help reduce some external noise, but they will not remove all sound. Performance depends on the noise source, distance, barrier height, density, position, installation and surrounding surfaces.

Noise can also travel over the top of a barrier, around the sides or through other routes into the building. For this reason, barriers should be selected as part of a realistic noise reduction plan.

Choosing the Right Acoustic Barrier

The right barrier will depend on the site and the type of noise involved. A home beside a road may need a different approach from an industrial site with plant equipment or a venue managing external customer noise.

Acoustic Supplies provides acoustic fencing and barriers for external noise reduction, along with a wider range of soundproofing products for walls, floors, ceilings, doors and acoustic weak points.
