Noise level of a 1.2m band saw were measured during the idling state and while cutting. Results obtained are as follows : (1) Noise levels during cutting are about 10 dBA higher than during idling. (2) The sound pressure level at higher frequencies dominates the overall noise level both during idling and cutting. (3) Noise produced by friction and the impact of the blade on the band wheel was the dominating factor in overall noise level during idling.
