"This article deals the numerical method to solution of sound propagation radiated by vibration of surfaces of machine complex. As the base of applied numerical solution is used the boundary elements method. The purpose of the work is to determine the rate of inaccuracy of numerical results obtained using the simple approach of BEM and also the estimation of its usability to finding the acoustical properties of machine parts. To fulfil the purpose the solution of acoustic problem was done using two approach of BEM. The average relative error of acoustic pressure level has value about 5%, , unique maximum value is 16 %."@en . "83-60102-30-9" . . "Ro\u010D. 31" . . . "2006-06-16+02:00"^^ .
