Rail Noise | Mass Transit Noise | Sound Panels Solution

Acoustiblok All Weather Sound Panels® Rail Noise Solutions 

Acoustiblok All Weather Sound Panels®  Rail Noise Solutions were successfully used to resolve a noise problem on a new rail line running through a community in Washington, DC. The company building the rail line is L.G.S., a joint venture of Lane Construction, Granite Construction, and Slattery and Skanska, Inc.

The panels were easily attached through stainless steel U-bolts to an existing railing, eliminating the need for a very expensive permanant concrete barrier. In addition, the concrete barrier would reflect the sound back, hitting the higher part of the train and then reflecting over the top of the wall into the community. Thus the value in the absorption of the sound, and not just the blocking.

Sound reflects off everything in all directions, just as light does,
even trees and foliage scatter and reflect sound. 
Rail Noise Solutions
  Virtually all rail line sound (noise) emanates from the wheel making contact with the rail.   The barrier wall absorbs no sound, and reflects it back into the side of the rail car, which in turn reflects it all right over the top of the barrier.    

As one can see, it's not how good the barrier is at blocking the noise (the STC). The real problem is how to stop the noise from reflecting off of the barrier. Using the Acoustiblok "All Weather Sound Panel ®" Rail Noise Solutions instead of a barrier not only blocks the "line of sight" sound, but even more important, it absorbs virtually all of the sound such that it has no reflections.
