Description/Abstract

Previous work on modelling acoustic transmission through the walls of rectangular ducts has left some open questions about structural damping, radiation damping and the way in which the acoustical radiation should be treated. In an attempt to provide answers to these questions a new numerical theory for the problem is described in this paper. It is both complementary to, and more accurate than, the simpler models described elsewhere. The results are gratifying, being in good agreement with measurements, both in detailed and in overall descriptions of the transmission phenomena. The numerical results are generally in close agreement with those of the previous theoretical approaches, providing some justification for several of the approximations implicit in those models.
