摘要: The problem of acoustic scattering from a curved interface between two homogeneous media is formulated as integral equations relating the normal velocity and potential at interface. are so chosen to minimize coupling. When γ, ratio densities, goes zero, decouple, one becoming equation soft‐boundary problem, other hard‐boundary problem. For small an approximate solution constructed by perturbation methods solutions related soft‐ problems.
