Certification of workplaces for working conditions at the woodworking enterprises shows that one of the major harmful factors of production is the production noise created by the woodworking equipment. Noise characteristics of woodworking machines depend on conditions of cutting of wood as the noisiest technological process of processing of wood is cutting process. The theoretical analysis of emergence of noise of the machine when cutting wood allows only in general qualitatively to determine a dependence of sound power on change of power parameters of cutting. In work it is suggested about direct proportionality of the radiated sound power from the energy spent for cutting of wood. Dependences of change of noise characteristics of machines on change of conditions of cutting of wood are as a result received. Amendments on change of levels of sound power of the machine in decibels are consolidated in look-up tables.
