Abstract: On the basis of the acoustic radiator field calculation method in the stratified space that was suggested by L. M. Brekhovskikh, we obtained field calculation correlation for a multifield model of radiators. Moreover, the results of numerical experiments are quoted which prove the possibility of application of expression when calculating radiator fields in space in case their direction should be taken into consideration.

Keywords: multifield model of radiators, radiator field in the semispace, wave-guided sound spreading.
