Sound Proof Your Home With Gabions

Updated: Jun 20, 2019


Do you own a home that may be ideal in every way, except for the sound from passing traffic? If you have a home or business located on or near a busy road, the noise can be a real problem. It can interfere with sleep, rest and conversation and cause irritability, headaches and stress. There are ways noise can be reduced inside your home, from using glazing on the windows and insulation in the walls. There are also certain types of noise reducing walls and fences that can be built around your property that can help significantly reduce the sound of the traffic.

Noise from heavy traffic can be up to 80db and as this simple infographic below shows (courtesy Gabion1) a traditional meter thick Gabion wall will substantially reduce sound compared to other types of walls and fences. Gabions are an ideal choice as they diffuse, absorb and reduce traffic noise, with the sound unable to pass under or through the thickness of the stonewall. Sandbags are also often incorporated into the traditional wire Gabions, increasing the sound absorption. Traditional Gabions therefore provide greater noise protection, even without added sandbags. Our slimline Rockweld fencing however, will still help reduce sound in comparison to other traditional types of fencing. This type of fencing has the added benefit of being fire proof (unlike brush fencing), an undesirable surface for tagging, as well as being a very strong and durable structure. In the unfortunate event of a vehicle crashing into the fence, the fence will stay intact and standing! You can see the difference between the traditional wire Gabions and Rockweld noise walls on our website.


Ideally the wall or fence needs to be high and wide enough to create a large enough 'acoustic shadow'. This 'shadow' is the area created from the noise barrier, which blocks the flow of sound waves to the home (see diagram below from www.nudec.cat). To be even more effective, fences also need to extend down side boundaries, or be long enough to provide at least 160° of protection.




Gates are also an important feature. They need to preferably be constructed from a dense or solid material that will also reduce noise. It is important that there are little or no gaps underneath or on either side of the gate, as gaps will allow sound to pass through. A fence that has a return back to the gate creating an alcove, will also provide extra noise protection.

The owners of this home on a very busy corner of North East Road are very impressed with their Rockweld fence saying that it has reduced the noise by at least 50%. The extra wall inside the gate added as a Feng Shui feature wall, would also have the added bonus of helping to reduce noise.
