How does acoustic fencing work?

Whether it’s noisy neighbours, the sound of busy roads or the hubbub associated with commercial premises, acoustic fencing is the ideal solution in a wide variety of situations.

In virtually every application for an environmental noise barrier, at least one reflective plane will be present from which sound can be reflected by introducing a barrier of sufficient mass, the way sound travels is disrupted therefore reflecting it off the face of the barrier.

the Effectiveness of an acoustic barrier

The effectiveness of an acoustic barrier is determined by five main factors:

- Material Density

- Barrier Construction

- Barrier Height

- Distance between noise source and receiver

- Relative height of source and receiver with respect to barrier

Material density and barrier construction relate to sound transmission in practical terms, the greater the mass of the barrier the less the sound. However, the structural integrity of the barrier is critical to its performance as gaps will allow sound to find a direct path through the barrier – therefore it is vital that acoustic fencing should be constructed with no air gaps and sealed to the ground to prevent sound leaking through. On top of this, acoustic barriers should be placed as close as is conveniently possible to the source of the noise to obtain optimum performance.

Available styles of acoustic fencing


  • 12k Acoustic Envirofence: Lighter than our usual Jakoustic® fencing, 12k Envirofence® is perfect for installations where the required noise reduction is lower that which would be provided by the standard Jakoustic® range.
       
  • Jakoustic® Reflective: Our Jakoustic® Reflective barrier uses heavy section planed timber boards to reflect noise away, reducing noise by up to 28dB*. With anti climb and scale design, Jakoustic® Reflective offers both privacy and security and comes with a 25 year Jakcure® guarantee.

  • Jakoustic® Absorptive: Jakoustic® Absorptive is a perfect solution where a noise source is in a tight confined area and surrounded by reflective surfaces. The barrier features an absorptive layer made up of Rockwool fibre and a protective membrane to reduce noise by up to 32dB.**

  • Jakoustic® Commercial and Highway: Designed for commercial and highway use, our Jakoustic Barrier provides noise protection whilst also complying with the stringent Highways Agency standards BSEN 1794-1 & 2 and utilises steel I-beam posts.

  • Trident® High Security: Trident® Jakoustic 2 and Trident® Jakoustic 3 provide a blend of noise reduction and high security. Trident® Jakoustic 2 combines Jacksons acoustic fencing with steel mesh lining making the fence difficult to scale or penetrate whilst Trident® Jakoustic 3 features a high security mesh interlining to maintain an attractive ‘natural’ appearance.

  • Acoustic Gates: Our acoustic gates ensure maximum effectiveness when integrated with Jacksons acoustic fencing. Available as swing or sliding gates and manual or automated operations.

  • *Jakoustic® barrier certified laboratory results: Rating according to BS EN 1793-2:1998 Category = B3 Laboratory sound reduction 28 dB Superficial mass 25kg/m²

    **Jakoustic® Plus barrier certified laboratory results: Category B3 rating according to BS EN 1793-2:1998
    Category A3 rating according to BS EN 1793-1:1998
