Who doesn’t love to shout in a canyon to hear their voice echo back to them?
Even a youngster grasps the concept of reflected sound, and understands you are “hearing the sound twice.” While it may be fun in that situation, that echo is actually sound being reflected off a hard surface – and that phenomenon is an unwelcome problem when trying to eliminate unwanted environmental noise.
Sound Absorbing Wall Panels
Nobody wants to hear more unwanted noise.
While most traditional environmental noise treatments have focused around reflective sound wall designs like concrete or wood, the persistent issue of reflected noise has driven the development of sound absorbing sound walls and noise barrier wall installation.
In essence, a sound absorbing panel that contains a porous face allowing sound waves to enter, and additional internal components that further diffuse or “absorb” the sound waves to prevent them from reflecting, is known as an absorptive sound wall or noise barrier.
