On the use of a Wave Based prediction technique for steady-state structural-acoustic radiation analysis

Conventional element based methods for modelling structural-acoustic radia- tion problems are limited to low-frequency applications. Recently a novel prediction tech- nique has been developed based on the Tretz approach. This new wave based method is computationally more ecient than the element based methods and, as a consequence, can tackle problems also at higher frequencies. This paper discusses the basic principals of the new method and illustrates its performance for the two-dimensional radiation analysis of a bass-reflex loudspeaker.
