What happens here

The final step involves taking another decibel reading from the patio area after completing the entire sound barrier system. The reading shows a significant decrease in noise, from the initial 76 decibels down to 73 decibels. While not a massive drop, it indicates a noticeable improvement in sound reduction, confirming the effectiveness of the multi-layered approach using earth, concrete, cement board, new fence panels, and landscaping. The presenter notes that combining these elements, including large and bushy plants, contributes to reducing sound transmission.

Goal: Assess the overall effectiveness of the sound barrier by measuring final noise levels.

amazing. We did everything we could, and it looks incredible, but the main question is: have we really made significant progress and what we wanted? So, let's turn to our indicators. 92. Okay, 92, and 95 is the number to beat. With embankment and retaining block—77 decibels. Okay, all things considered, our score is 73. But to see if this really works, we need to replicate our original experiment. Chad will take my truck with the same exhaust system, keeping the same speed, and we will see what the results are under this patio. 76. It was a 76 with a loud exhaust that cuts through everything. And 92. Okay, 92, and 95 is the number to beat. Well, we lowered our rates. They are not as low as I had hoped. The density of this fence would have been much better with a concrete wall, but the quarter inch, double layer, and mound significantly lowered our numbers, and I am very pleased with the result. If you have other alternative solutions for reducing noise that definitely work, I'd love to hear about them in the comments below. In the meantime, here's a video that I think you'll like.
