Raised External Acoustic Noise Barrier

As any landscape professional already knows, installing trees and vegetation as a visual berm between roadway traffic and residences may be aesthetically pleasing, but these elements are not effective noise control barriers. Acoustiblok, a leader in noise abatement for both internal and external installations, has been successfully supplying AcoustiFence External Barrier Membrane, a revolutionary new defence against outdoor noise pollution for many years to all sectors.

The fact is, foliage or trees on earth berms can actually increase noise. Since sound is dispersed in much the same way as light, it will penetrate and reflect off the foliage and tree limbs (urban resonance) in all directions, including that side of the berm that is meant to be peaceful and quiet. Although the higher the berm, the better the sound deflection, it is far more affordable and more practical to increase the berm height by installing AcoustiFence than it is to add additional height to the berm.

Adding just a 1.82m high AcoustiFence to the berm not only drastically increases the berm’s blocking protection, it eliminates the sound reflecting off the foliage and into those outdoor spaces that are meant to be serene. The all-weather AcoustiFence can be hung from any substantial structure, such as a chain link or wood fence, or from a pipe frame structure.

 

 

 

 

 

 

 

A simple and economical noise abatement solution for both residential and industrial usage, AcoustiFence is a 3mm (1/8-inch) thick material measuring 1.82 metre (6′) high by 9.14 metre (30′) long with brass eyelets around the perimeter along the top, bottom and ends for easy attachment to any chain link fence or other framework. Easily installed and removed in less than one hour, entirely impervious to mould and mildew and UV tolerant, AcoustiFence fitted correctly is virtually indestructible, making it a one-time purchase that never needs replacing.

The soundproofing material in AcoustiFence is made from a proprietary formula of the Acoustiblok^® Corporation, developed and refined over an eight year period for various applications. Acoustiblok is recognised and sold world-wide, earning product awards from the British House of Commons, as well as industry publications including Builder News Magazine and others.

AcoustiFence has proven performance in highway environments, construction sites, offshore oil rigs and waste-to-energy plants. AcoustiFence can accommodate any height fence or structure by simply overlapping the AcoustiFence panels. At a construction site, it can be attached to scaffolding or the building structure itself. To store, the AcoustiFence panels simply roll up like carpet.

Independent lab tests of the AcoustiFence material show an STC of 28, which represents to the human ear an approximately 85-percent reduction in sound. However, results will vary relative to surrounding sound-reflective objects such as buildings, machinery, and industry equipment, and the amount of AcoustiFence installed.

AcoustiFence is 100% recyclable, an environmentally friendly answer to the problem of outdoor noise pollution.

Acoustiblok, Inc. President Lahnie Johnson believes the application potential of AcoustiFence to landscaping projects is endless.

“This very simple, economical sound abatement product will be extremely popular in new and existing landscape settings thanks to its unequalled ability to reduce unpleasant exterior noise, allowing a better quality of life for anyone living on the other side of a highway or any invasive noise source,” he said.

“After all, our mission is “quietening the world” and “breaking ground in reducing sound”.
