The problem of coupling between vibration of elastic structures and produced soundn is discussed in the paper. The shells of revolution are considered as the elastic structures. The Finite Element Method (FEM) is used for calculation of the vibration, and the Boundary Element Method (BEM) - for calculations of sound radiation. Themixed FEM-BEM-method for calculations of vibration coupled with sound radiation is described. Two variants of this method have been developed. The numerical example - the vibrating circular plaet immersed into air - is presented.
