Engineers turn down conveyor noise designnews

2001-3-26  Noise levels generated by a typical lineshaft conveyor system-whose sources of noise include shaft clatter, bearing rattle, and roller tube ringing-can exceed 70 dBA. By applying various noise reduction strategies in this newest generation of conveyor systems, engineers have been able to achieve decibel levels in the low 60's-all the more impressive when you consider that decibels are logarithms of noise levels.
