TI - On the use of a wave based prediction technique for steady-state structural-acoustic radiation analysis T2 - Computer Modeling in Engineering \& Sciences PY - 2005 VL - 7 IS - 2 SN - 1526-1506 AB - Conventional element based methods for modelling structural-acoustic radiation problems are limited to low-frequency applications. Recently, a novel prediction technique has been developed based on the indirect Trefftz approach. This new wave based method is computationally more efficient than the element based methods and, as a consequence, can tackle problems also at higher frequencies. This paper discusses the basic principles of the new method and illustrates its performance for the two-dimensional radiation analysis of a bass-reflex loudspeaker.
