The effects of noise can have damaging consequences and efforts should be made to minimize noise exposure. Reduction of noise produced by vibratory feeders is one area that can significantly reduce noise exposure in the workplace.
The SPIROL Series 2000 Vibratory Feeder is quieter than conventional vibratory feeders. Empirical data to support this claim was gathered by conducting comparison testing between a conventional square drive and a SPIROL Series 2000 drive. Measurements and analyses were performed by Noise Control Engineering (NCE) of Billerica, Massachusetts. The same bowl was used for testing on each drive. Noise readings were taken with an empty bowl, plastic bottle caps and metal coiled pins. Consistent feed rates were maintained between the Series 2000 and the square drive for both the caps and the pins.
Four measurements around each vibratory feeder were taken and averaged in order to compare the square drive to the Series 2000.
