Outdoor noise pollution is a serious problem, and it affects some people more than others. If you reside near airports, motorways, industrial establishments, or railways, you’ll have to bear with unwanted sounds. When exposed to noise pollution for prolonged periods, people tend to develop various physical disorders, including stress, hypertension, and heart disorders. Fortunately, there are ways to reduce or even block the sounds completely, and one of those ways involves installing an Acoustic Barrier Fence. However, you also have to consider several factors, such as the sound you’re dealing with, its intensity, power, pressure, frequency values, and dB levels.
About the solution
So, what do you need to know about acoustic fencing? It’s a system that you can install to reduce environmental sounds generated by high levels of vibration and other sources of excessive noise. If the fencing is of top-notch quality, it can be surprisingly effective against the sounds generated by noisy machines, heavy traffic, and commercial activities. It can also work to ward off the noise created at sports venues, factories, and railways. This particular type of fencing can reduce noise by approximately twenty-eight decibels. Of course, the level of efficiency of the fence depends on the location where you install it. These barriers can be of two types. The first variant is reflective while the second is absorptive.
The difference
Is an acoustic barrier fence better than a regular fence? If so, what are the differences? First of all, a soundproof fence should possess a surface mass density of at least ten kilograms per square meter. Manufacturers create these barriers based on the principles of deflection through enough mass and density, which is the main reason conventional solutions are thicker and heavier. At these levels, you can expect the fence to deflect unwanted noise back instead of letting it travel through the material it crashes against. Standard fences crafted using timber slats will do the job, but they may have a few holes or gaps. Make sure that the installer does something to close them.
Sound-blocking effectiveness
As mentioned above, every type of Acoustic Fencing should possess a surface mass density of at least ten kilograms per square meter. Only then the mass and density of the substance used in crafting the barrier will be able to block sounds and deflect the same. It’s best to stick to flexible soundproofing material made of a thin yet high-performance acoustic membrane. This membrane should be easy enough to attach to an existing structure or support, such as a wooden fence. This particular material is extremely thin, but you shouldn’t make the mistake of believing that it’ll fail to do the job. It can reduce sound reverberations and ingress beyond all expectations.
Alternatives
You’d probably want to use an acoustically-rated material to build your fence if you wish to cut off unnecessary noise while maintaining aesthetics. However, such solutions tend to be expensive and time-consuming to install. You can resort to innovative acoustic materials available in the market, of course. You’ll need an intact fence to incorporate these options. These materials are easy enough to set up on an existing perimeter fence or standard substrates, such as chainlink, post & rail, heras, or hoarding fencing with or without grommets.
