Abstract
A bidimensional mathematical model has been developed to study the pro pagation of acoustic waves in waveguides. This paper presents the theo retical formulation and its application to a rectilinear elastic wedge , which top angle is variable. Comparison between finite element resul ts and empirical or experimental results demonstrates the accuracy of the model. Then, the method is extended to curved waveguides.
