Do highway noise barriers work?
Studies show a sound wall are more effective sound-reflective sound barriers. Such innovations ensure freeway sound walls reduce sound levels and provide a cost-effective solution to highway noise pollution.
Why are there holes in highway walls?
The principal purpose of these is typically to provide citizens with a visual barrier to the highway and sometimes to mitigate traffic noise. Today, highway barriers cover thousands of miles of federal roadways.

What is the difference between a barrier wall and a drainage wall?
So, a barrier wall system, unlike a drainage wall system, a barrier wall system is really designed to stop all water at the exterior face of the wall. So, there would be no provision to manage any water that got behind that exterior plane of the wall.
How effective are highway sound barriers?
Every additional meter above the line of sight reduces the sound by an additional 1.5 decibels. This works through reducing the amount of sound energy able to pass over the wall via diffraction. Thats it. Yes, thats actually 99% of the science behind the highway sound barrier.
