Sound Absorbing NoiseWalls designed to reduce reflected noise from highway, railway and airports .     WHISPER WALL Noise Barriers reduce noise levels for people living next to highways, either by absorbing sound energy or by reflecting sound energy. Both methods work, however, sound absorption is more efficient and less likely to produce unexpected results. Sound absorbing noise walls allow sound waves to enter the wall, as the sound waves travel through the sound absorbing mixture they are forced to change direction and follow a longer path. Every change in direction decreases the sound waves energy. After the sound waves completes its journey through the wall, little, if any sound energy remains to reenter the environment. In comparision, reflective noise walls abate noise by redirecting sound waves into the atmosphere. This is risky because reflected sound waves traveling through the atmosphere bend upward or deflect downward depending upon existing meteorological conditions. Consequently, as atmospheric conditions change , the accuracy to predict how reflected sound waves travel decreases. This explains why some residents living across from a reflective noise barrier may experience new sounds and / or increased noise levels. Whisper Wall does more that absorb sound, it has also been test for blast mitigation and penetration of small arms fire Lynnhaven Parkway, Virginia Beach, Virginia LICENSED WHISPER WALL MANUFACTURES Environmentally engineered,WHISPER WALL absorbs sound using a highway generated waste product, RUBBER VEHICLE TIRES. Rubber tires are recycled and processed into small chips, the rubber chips are then blended with  natural sound absorbing aggregate and cement to produce our patented sound absorbing mixture. Whisper Walls unique composite barrier is recognized as one of the most durable sound absorbing noise walls manufactured. Whisper Wall has proven its superior durability in all types of climates throughout the USA, Canada, and Puerto Rico. Whisper Wall has also been tested for blast mitigation and small arms petentration.  For a Whisper Wall Manufacture near you, PUSH  or phone  703-222-9702 or E-mail:  Info@Whisper-Wall.com Concrete Innovations licenses its Whisper-Wall technology to qualified concrete precasters.
