APPLICATION OF THE FINITE ELEMENT METHOD IN THE STUDY OF ACOUSTIC FIELDS
The paper considers the possible application of the finite element method to construct acoustic fields in 2- and 3-dimensional spaces. Examples of the numerical simulation are given, as well as the comparison with the results of the real experiment and with the re-sults of Finite Difference Time Domain application. Close agreement is achieved for both wave fronts and velocities of various wave types.
