The formation of noise at the workplace of the operator due to the interaction of the individual noise sources, which are the units and components of machinery and equipment used in technological processes. In such processes the system noise sources can be considered as a closed physical system. Circuit occurs or the infinitely remote region where the noise is absorbed, or boundary surfaces, of which the noise can be partially reflected and aproximates secondary sources of noise. On the other hand it is known that the noise level arising from several nekogerentnogo sources operating simultaneously is calculated on the basis of the principle of energy summation of the individual radiation sources. In the article the mathematical model of the formation of noise at the workplace the interaction of sources of the noise caused by individual nodes and aggregates of machinery by the machinery included in the technological complex allows to define the processes establishing the stationary energy levels of the noise and calculate the noise level at the workplace of the machine operator.
