Although maximum permissible exposure limit for noise set by OSHA is 90 dBA, a range of 50 to 60 dBA is actually considered comfortable. 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.

Conveyors near noise-sensitive zones, that is, homes, etc., require a noise contour map. This will show the noise levels between the sensitive zone and the conveyor. The options are then: • Reduce the noise at the source. • Barriers. 20.5.1.2. Roll and belt surface. The roll and belt surface profile play a key role in generating noise.
