2012-8-29 each identified noise source independently. The conveyor was found to be a dominant source of noise. The noise level due to the conveyor was affected by the tension in the chain, with higher tensions resulting in higher noise levels. It was also determined that running the conveyor in wet conditions reduced the sound level significantly.
