適用范圍：The document describes the physical backgrounds of low-noise design rules for machinery and equipment given in DIN EN ISO 11688-1. It thus serves to detail the EU machinery safety directive (89/392/EEC). This standard explains the sound generation and propagation mechanisms in machinery, equipment and vehicles. It is distinguished between internal sources, transmission paths inside the machines and radiation from its boundaries. The document contains a glossary with definitions of thirteen terms.
