Abstract (EN): A great deal of information on damping technologies is nowadays available for the practical reduction of machinery noise, in general, and circular saw blades, in particular, for woodworking operations. However, some of these noise reduction techniques are not gaining widespread acceptance, which possibly can be explained by lack of information/interest by the developers and end-users. The need for continuing dissemination and research of more efficient and appellative noise reduction techniques for low-noise woodworking circular saw blades immediately emanates from the foregoing. The use of viscoelastic damping technologies is one possibility to reduce the radiated noise levels from circular saw blades. These technologies are considered in this article. A coupled vibroacoustic finite element analysis is performed in order to gain further insight into the design and applicability of viscoelasticbased noise reduction strategies considering also the centrifugal stiffening effect due to the rotation of the saw. The widespread use of low-noise ("quiet") circular sawing industrial practices for woodworking is assessed and promoted.
