Acoustic Noise Barrier Factory

Brand:Shengcheng

Product detail: Sound noise barrier feature: 

Effective noise barriers typically reduce noise levels by 15 to 30 decibels (dB), cutting the loudness
of traffic noise by as much as one half.

For example, a barrier which achieves a 15-30dB reduction can reduce the sound level of a typical
tractor trailer pass-by to that of an automobile.
