Acoustic Fencing: What Is It and How Does It Work

The purpose of acoustic fencing is to reduce noise levels within a space by reducing the sound level. There is a type of fence called a soundproof fence that acts as an insulator, preventing sound waves coming in from the outside environment and, as a result, creating an environment that is soundproof. In many cases, they are employed by businesses, homes and even schools.


Using this guide, you will learn everything you need to know about acoustic principles as well as how to install acoustic fencing in Brisbane. Furthermore, we also have an article detailing different ways in which you can soundproof your garden if you feel like going the extra mile.


Noise pollution can reach overbearing levels in large cities and places with a high level of commercial activity, even in residential areas. In these areas there is evidence of increased stress levels, sudden headaches and even problems with sleep.


Even the WHO recommends that background sound levels should not exceed fifty decibels (50dBA) in our daily lives, which is often exceedingly high. You may find that leaving your workplace and going home to an environment that has relatively high noise levels will affect your efficiency as a whole and your performance at work. This is where soundproof fencing comes into play.


How Does Acoustic Fencing Work?

Sound waves basically travel in a straight line. Sound can therefore be reflected, refracted or conducted based on the material properties. Thus any obstacle between the wave paths will potentially obstruct the wave and thus reduce its energy level.


Any sound coming from the external environment such as car and engine sounds, children playing, partying, animals etc will all go in a directed path to your house except if an object stands in its way.

4 Types of Acoustic Fencing


There are several types of acoustic fence available. The type of materials used directly affects the quality of noise reduction obtainable.


1. Wooden Fence (Most Popular)

A strong wooden fence without any spacing can adequately mirror the noise from the street. The thicker the wooden fence, the better it becomes in mirroring the commotion. The wooden fence ought to be thick and strong enough to be used as a strong boundary fence. Cedar and redwood are great choices to construct a wooden soundproof fence.


Wooden fences are less strong and may show signs of wear and tear after some time due to local weather conditions. Proper insulation of the wooden fence against the weather will play a significant role in lengthening its life span.


2. Metal Fence

There is no uncertainty that metal fences are strong and provide high quality soundproofing. A layered metal fence is another alternative to soundproof the fence. Consider purchasing water-safe and erosion safe metal or metal compound to manufacture the fence.


3. Concrete Soundproof Fence

Clearly stones or blocks can stop most of the sound waves because of their thickness. The most common structural material on the planet is concrete. Many projects requiring soundproofing have made use of concrete due to its capacity to reduce noise levels. A solid soundproof fence is a strong obstruction fence worked from rock and concrete.

4. Brushwood Fence

Another type is the brushwood fence. Brushwood walls are made utilizing twigs, little branches, and undergrowth. Building a thick brushwood fence can give some measure of noise reduction. The thickness of the fence must be more than 60 cm to be powerful enough.
