Abstrakt: In this paper, we describe a method for solving the problem for calculating the acoustic radiation of a deformable solid oscillating in a compressible fluid by using the mode analysis procedures found in mechanoacoustic systems. The method is based on an approximate representation of the acoustic radiation loss function and modifications of the Lanczos method. This allows constructing an efficient computational algorithm for finding sound-emitting forms of resonant oscillations and the corresponding complex values of eigenfrequencies. The developed method was tested using a model problem as an example. [ABSTRACT FROM AUTHOR]
