Temporary Sound Barriers 30dB noise Reduction Materials 4 layers + colour green cut Any Size

A sound acoustic barrier without any added absorptive treatment is by default reflective. In highway applications, for example, a reflective noise barrier on one side of the roadway can result in some sound energy being reflected back across the roadway to receivers on the opposite side. In this situation, it is a common phenomenon for one to perceive a difference in sound after a noise barrier installed on the opposite side of a roadway. Individuals on the opposite side of the roadway may perceive a change in the quality of the sound; the signature of the reflected sound may differ from that of the source due to a change in frequency content upon reflection. The best way is to combine both absorptive material and reflective material. That is how our mass vinyl acoustic barrier was developed. They can conform to the shape of your chassis, or for more intricate areas, can be moulded with a hook. It’s quite flexible.
