Abstract
An experimental investigation was conducted of the effect of important geometric and kinematic parameters on idling saw blade noise. Blade tip speed is determined to be the dominant factor in the noise production. Variations in blade geometry, which included the number of teeth, the blade thickness, and the tooth gullet shape, produce secondary effects in the radiated sound on the order of 6 decibels. Results suggest that the sources are likely to be compact and are dominated by the unsteady forces acting on the tooth surfaces resulting from the interaction of the tooth and the incident unsteady flow in the wake of the preceding tooth.
