Abstract : The predicted properties of the Stoneley- Scholte wave, deduced from a previous theoretical study, are experimentally verified at the boundary between an ideal fluid and a viscoelastic solid, respectively represented by water and synthetic resins PVC and B2900. In particular, it is quantitatively shown that the damping of the energy of the interface wave increases with the distance from the interface and with the distance of propagation. The method of generation of the Stoneley- Scholte wave is based on the association of a shear wave transducer with a solid wedge. The method, previously developed for the ideal fluid-elastic solid interface, is here adapted for the boundary between water and a viscoelastic solid.
