Abstract: In order to understand the noise level and peculiarities of the present woodworking machines, noises made by three major general purpose woodworking machines, i, e., saws, planing machines, shapers and tenoner were measured. Meanwhile, frequency spectrum analyses of noises from some of these machines were also made. According to the results measured, analyses of noise source, noise frequency peculiarity, directionality and the major factors influencing noises have been made, thus providing a reference to controlling and abating the noise of woodworking machines.
