Relation between such factors as a noise level, air flow rate and incoming hole size were considered. The aim of investigations is to obtain the chart and analytic equations for determination of the necessary incoming hole size (diameter or width and height) under condition of the necessary amount of air satisfaction at the rated noise level. There are presented results of investigations with interaction of opposite non-coaxial of air jet's acoustic characteristics, which give possibility to make a control of air supply devise choice at air distribution calculation. Dependence of noise level from jet's leakage velocity and size of air supply devise has been investigated.
