Few Years back, I got shifted to my new home on the outskirts of the city just to live in peace away from the traffic noises which are always striking the eardrums. But after an year, the outskirts started to develop more and more. Lot of population hopped in which created the same city effect from which I ran away just 3 Years ago.

I was very upset from the fact that I moved to this new house in search of peace which got snatched from me after an Year. I started thinking that is there any place on this Earth where I could stay connected to my people and work but sit back in the Backyard relaxing in peace?

No, my mind said. Then I decided to take on this project to Soundproof my backyard from the traffic noise outside. But when I searched on the Internet to reduce traffic noise in Backyard, you wouldn’t believe me, there wasn’t a single website telling me exactly how to do it and what ways will be effective to get nearly 80% silence from the traffic noise on the street.

Then I started reaching out to the architects and Soundproof experts in town to know more about How soundproof a backyard? It got me a few weeks to chose the right way to Soundproof my backyard completely. As There was not a single answer, there were plenty according to our needs.

How Soundproofing your backyard works?

There are Two types of products that work in reducing the road noise in the garden. The science behind these products are 1. Sound deflection & 2. Sound absorption. You need to understand these two phenomenons before getting your hands on soundproofing Backyard.

  • Sound Deflection

Let’s first ask you a question. Does the intensity of traffic noise is way higher? or you have a high budget to get rid if the traffic noise? If your answer is a ‘yes’ then this category is for you.

What happens in sound deflection is that the material used to fence your backyard deflects the sound back to the source from which it has emerged. This method of Soundproofing is best suited if the noise issue is big enough. As it Soundproofs the backyard better than the secondary option you’ll hear below and what I have used in my Garden. Sound deflection quality varies in material to material. Usually this quality is present in stones & bricks as they are tough and dense enough to deflect the sound back.

  • Sound Absorption

Now comes to thing you were looking for. As most of us don’t have the high budget to install a brick or stone wall in the place of your existing fence. So here’s the phenomenon of Sound absorption on which our most of the products will be based on. Before moving forward, let me tell you that it will not perform as good as sound deflection.

But the happy thing here is that we can get nearly the same effect if we select the right products and combine and apply them the right way which will cost half to the brick wall. Wasn’t it some Superb Information?

Below I’ll tell you how exactly I was able to get as near as 60%-70% of reduction in traffic noise which is a massive change. Be tuned with this article and read every line carefully to avoid any mistakes further.

  • Fence Height is the key

The height of the fencing is one of the most important factor everybody forgets to take care about. What you need to do is analyze the height of the sound waves coming towards your backyard from the respective Cars. Usually the height of the sound waves reach up to 4.5′ feet. So you need to build your fence up to the height of 6.5′ feet so that sound waves wouldn’t be able to bounce off the fence.

  • Thickness to defend the Noise

Thickness is the other factor which leads to poor soundproofing and doesn’t create a difference if not kept in mind. The more thick the fence is, the more it will be effective in reducing and absorbing the noise interrupting your peace.

  • No cracks = No Leaks

Yes, as you would have understood from the heading ‘NO crack= NO Leaks’. What you have to do is to avoid the bottom gap between the ground and the fence. As the sound can easily leak through any cracks inside the fence or the gap below it. You have to cover everything with the products.
