Abstract: In this paper, an analysis of the interaction of steady longitudinal waves with an annular part through a oraok located in an infinitely long hollow cylinder has been investigated. Using the integral transform technique, the problem is reduced to a second kind of Fredholm integral equation, which is then solved numerically. And finally, the feature of displacements at the far-field has been discussed in detail.
