If the foremost item on the agenda has been enhancing form stability, surface quality and tool service life, the SilEnT Project explored the options for reducing noise emission caused by the process on hydraulic punching machines. This article is a description of the potential particularly in the range of low-frequency eigenmodes of the machine frames that are important for noise emission.enaktive GeräuschminderungStanzmaschineGeräuschemissionMaschinenakustikactive noise controlpunching machinenoise emissionmachine acoustic620conference paper
