Noise generation in pneumatic blow-off guns
American Industrial Hygiene Association Journal
|December 1, 1977
Abstract:
An efficiency rating system is presented to aid in the selection of hand held air guns, nozzles, and ejectors. This guide is based on noise levels, force or thrust, and air supply pressure. In addition, air consumption, blocked static air pressure, noise directivity patterns and spectra are presented. Finally, noise control techniques in the use and installation of nozzles and ejectors are reviewed.
