| Abstract: | Numerical calculation of arbitrary two-dimensional steady sound field is developed with boundary element method, and used to obtain radiated field generated by a uniform pulsating cylinder and an oscillating cylinder. Numerical solutions of two examples are compared with analytical ones, illustrating the more effectiveness of BIE method in engineering acoustics. Program compiled is applicable to the analysis of arbitrary two-dimensional steady sound field. |
