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.
提出了一种效率评级系统，以帮助选择手持式气枪、喷嘴和喷射器。本指南基于噪音水平、力或推力以及空气供应压力。此外，还介绍了空气消耗量、阻塞静态空气压力、噪音指向性模式和频谱。最后，回顾了喷嘴和喷射器使用与安装中的噪音控制技术。
