What happens here

To create the primary sound barrier, an earthen berm is constructed along the fence line. The presenter uses a Ditch Witch mini skid steer with a bucket attachment to move existing dirt and create a raised mound. The berm is built about 2-3 feet high directly against the fence. Water is sprayed onto the dirt to reduce dust during compaction and to help settle the soil. This step highlights the concept of using dense mass (earth) to absorb sound waves. The presenter also notes the presence of concrete debris in the dirt, which is used as fill for the berm, showcasing resourcefulness.

Goal: Build a dense earthen berm to absorb low-frequency sound waves.

Tools and materials

  • Ditch Witch Mini Skid Steer Ditch Witch — Moving and shaping large quantities of dirt for the berm
  • Plate Compactor — Compacting the earthen berm to increase its density and sound blocking effectiveness
  • Respirator Mask — Respiratory protection from dust during excavation and compaction
  • Safety Glasses — Eye protection from dust and debris
  • Water Hose — Wetting down the dirt for compaction and dust control
  • Dirt/Earth N/A — Creating the mass of the berm

, baby. So, if we start thinking about sound waves, the first thing that comes to mind as the most budget-friendly option is the earth. And we are lucky, because we have a lot of it. My theory is this: if we start by building an embankment, all vibrations within 2 to 3 feet of the embankment will be absorbed by it. That's what I think. And that means that's exactly what we're going to do. Let's begin. Oh man, I didn't think about those cross panels welded to the 4x4 post. How the hell am I going to get this in here ? Another day where I have to think about how to get heavy equipment here. If you know me, you know that I've been in this situation before. Well, there's no point in crying about it. I'm telling you, we need to get ready, and we just picked out the right clothes today. So we're going to start cutting this thing down to get the machinery in here. Let's start, let's push hard! To the full? Press the gas all the way down . And what is gas for? If everything is going smoothly, then you are not building anything. Things have to go wrong and against you for you to be called a true master. I think this is the best place where the technology won't interfere with the rest of the project. There are three of them here. There is so much of this. Here it is. This isn't going anywhere. I've never worked so hard taking down a fence. Sir, whoever built this, I salute you. I can't get angry. A master will appreciate a master. You built a damn strong fence, sir. I want you to know this. I must inform our viewers that we have suffered a loss on the channel. This person was with us—well, "person" is somewhat limited—this figure was with us for 3 years and achieved many wonderful things. And today we say goodbye. Ariat are the best work boots I have ever worn. I built an A-frame cabin in the woods, renovated an abandoned house, and finally the boa lacing system on them broke. New shoes have arrived , and they are very comfortable. I'm walking around with a new outfit . And you know, I put insoles in there, because I'm an old man. So, we have a lot to do today. Don't get injured when you go to get injured. We have some bricks here. We spent a lot of money today, which I'm not thrilled about, but before we get to that, let me show you our mound. We are looking at 25 meters of pure beauty . It feels like we're preparing for a foreign invasion and war, and we need something to absorb the bullets. We have an embankment. Let's start ramming this thing. Did you plant…
