Abstract The noise produced by compressed air nozzles used in cleaning, transporting and ejecting workpieces can be significantly reduced by: carefully matching air pressure to the required force or air flow; selecting the adequate number and diameter of orifices; optimising the distance between the air nozzle and the workpiece. Examples show that noise reductions of 5 to 9dB can be realised. Twenty models of quiet nozzles are presented together with tables as application guidelines.
