QCIT Sound noise barrier feature: 
Effective noise barriers typically reduce noise levels by 5 to 10 decibels (dB), cutting the loudness
of traffic noise by as much as one half.
For example, a barrier which achieves a 10-15dB reduction can reduce the sound level of a typical
tractor trailer pass-by to that of an automobile.
