As the contemporary world is more densely populated than ever before, it is no wonder that acoustic fencing is highly in demand. From traffic to noisy neighbors, we are frequently surrounded by undesired noise.
With latest World Health Organization (WHO) research suggesting noise pollution can affect both physical health and mental wellbeing, it is important to realize the types of noisebarriers that can provide some invaluable serenity and peace.
Noisebarriers should be usually uncut to prevent any sound passing through gaps, and should have a minimum mass of 10kg/m2 as noise might pass through lighter materials. And also the possibility o block sound, it is worth considering other factors like cost, size, privacy, aesthetics, and maintenance. For instance, timber acoustic fencing and earth bunds mix conveniently into the natural ambience and work well for residential properties, while steel and concrete barriers might be better suited to industrial sites.
Wooden noise barriers

Wooden acoustic barriers also provide enhanced security with an anti-climb flat profile, and can be blended with steel for high security applications. Their versatility also covers noise performance, as timber barriers can be either reflective, or have an extra absorptive layer on one side. The can also be a system for road noise.
Wooden barriers should be made from kiln dried, pressure treated timber to make sure minimal maintenance and durability, and should come with a long guarantee. As timber stays uncut, wooden noise barriers will work well for many years.
Metal noise barriers
Metal barriers are robust, strong and usually offer up to a 28 dB noise reduction. For the barrier to work efficiently, the barrier should have a minimum mass of10/m2 to prevent any undesired sound leaking through.
Just like the wood types, metal noise barriers are available as both absorptive and reflective, though reflective can create a reverberation impact in some applications. Metal noise barriers are better suitable to industrial or commercial sites, as they are slightly less welcoming in outlook than wooden barriers, and it is worth remembering a coastal location, would need a marine coating on the barrier to prevent rust.
With such a wide range of noise barriers to select from, it is a challenge to be sure which the best for your site is.
