Acoustic Enclosures From Acoustic Supplies Can Quieten Noise

Acoustic Barriers and Enclosures for Outdoor Noise

Outdoor noise can make homes, workplaces and commercial sites less comfortable to use. Traffic, railway lines, machinery, construction activity, plant equipment and nearby industrial processes can all create unwanted sound that travels into gardens, buildings and neighbouring spaces.

Acoustic barriers and enclosures can help reduce outdoor noise when they are correctly specified and positioned. The right solution will depend on the noise source, site layout, distance from the receiver and whether sound is also entering through the building itself.

What Are Acoustic Barriers?

Acoustic barriers are designed to reduce the amount of sound travelling from one area to another. They are often used around roads, railways, gardens, boundaries, commercial sites, plant areas and industrial locations where noise needs to be controlled.

Acoustic fencing and barriers can help block or reduce the direct path of sound between the noise source and the area being protected.

What Are Acoustic Enclosures?

Acoustic enclosures are used to contain noise around a specific source. They may be suitable for machinery, plant equipment, generators, compressors, pumps, extraction systems and other noisy equipment.

Rather than treating a whole building or boundary, an enclosure can be designed to reduce sound close to the source before it spreads to nearby rooms, properties or external areas.

Traffic Noise and Roadside Sound Barriers

Homes and businesses close to busy roads can be affected by constant traffic noise. Cars, lorries, motorbikes and buses can all generate airborne noise that travels across gardens, driveways, boundaries and external walls.

Acoustic barriers may help reduce traffic noise where there is a suitable location between the road and the property. However, the performance will depend on the height, density, continuity and positioning of the barrier.

Railway Noise Reduction

Railway noise can include train movement, braking, announcements, vibration and general activity around tracks or stations. Acoustic barriers may be considered where a property or site is close to a railway line.

As with road noise, the barrier needs to interrupt the sound path effectively. Gaps, low sections or poor positioning can reduce performance, so the design should be considered carefully.

Industrial and Commercial Noise Control

Industrial and commercial sites may need acoustic control for machinery, loading areas, mechanical services, generators, workshops or plant equipment. Noise may affect staff, neighbouring businesses or nearby residential properties.

Depending on the source, suitable solutions may include acoustic enclosures, barriers, screens, doors, wall systems or other specialist soundproofing products.

Acoustic Barriers for Gardens and Boundaries

Outdoor noise can affect gardens, patios, driveways and external seating areas. Acoustic fencing or boundary barriers may help reduce noise from roads, neighbouring commercial sites or nearby activity.

For best results, acoustic barriers should be continuous and close enough to the noise source or protected area to interrupt the sound path. Open gaps, lightweight fencing and poor junctions can allow sound to travel around the barrier.

Sound Curtains and Flexible Noise Barriers

Sound curtains and flexible noise barriers may be suitable for some temporary or semi-permanent noise control applications. They can be used around certain work areas, machinery or site boundaries where a more adaptable solution is required.

The correct product will depend on the noise source, installation method, environmental exposure and level of reduction required.

When Outdoor Barriers Are Not Enough

Outdoor barriers can help reduce some external noise, but they may not solve every problem. Sound may still enter a building through windows, doors, external walls, roof spaces, vents or gaps in the building fabric.

If noise is mainly disturbing the inside of a property, internal soundproofing may also be needed. This could include wall, ceiling, floor or door treatment depending on the route sound is taking.

Wall Soundproofing for External Noise

If outdoor noise is entering through external walls, wall soundproofing may help improve the acoustic performance of the affected room.

Wall soundproofing products can help reduce airborne noise transfer through suitable wall constructions in homes, offices and commercial buildings.

Soundproof Doors and Weak Points

Doors can allow external noise to enter a building, especially where they are lightweight, poorly sealed or exposed to a noisy area. Gaps around frames, thresholds and door edges can all reduce acoustic performance.

Soundproof doors, acoustic seals and suitable threshold details can help reduce sound leakage through doorways and support wider noise reduction plans.

Windows, Vents and Openings

Windows, vents and other openings are often weak points for outdoor noise. Even where acoustic barriers are used outside, sound may still enter through older glazing, poorly sealed frames, air bricks, trickle vents or service penetrations.

These areas should be assessed before deciding whether outdoor barriers, internal soundproofing or a combination of both is required.

Choosing the Right Acoustic Barrier or Enclosure

The best solution will depend on the noise source, the site layout and the level of reduction required. A road-facing garden may need a different approach from a commercial plant area, industrial boundary or generator enclosure.

Key factors include the height of the barrier, the material density, the position of the barrier, gaps in the system, weather exposure and whether sound can travel around or over the treatment.

Soundproofing Products for Wider Noise Control

Outdoor noise control may need to be combined with other soundproofing measures. Acoustic Supplies offers a wide range of soundproofing products for external barriers, walls, floors, ceilings, doors and acoustic treatment in domestic, commercial and industrial environments.
