摘要：

A procedure is given which is to be followed when linking an acoustic finite element model to an absorption model. The procedure ensures both equality of pressure and compatibility of the normal velocity at the interface boundary. It is illustrated and tested by applying it to a one dimensional acoustic absorption system to calculate the absorption coefficient. Good agreement with an exact solution is shown. © 1979.
