摘要
Regarding woodworking machines, machine acoustics are of particular significance due to the high noise emission of these machines. Among other things, this can be attributed to the adoption of the European Commission Machinery Directive as a national law, which demands protection against noise emission in the design phase of new machines. In order to accomplish this, it is necessary to examine and locate the causes of emissions on existing machines. In this paper, the sound source is located through sound intensity measurements, using planing machines as an example, which are particularly noise-intensive woodworking machines. In addition, different influencing parameters on noise emission are analyzed, such as manual and automatic feed, rotational speed and the influence of the type of wood of the workpiece.
