Abstract
An investigation is made of the dynamics of a liquid free surface in the presence of a reflecting sound field. A finite-amplitude surface standing wave is also specified and the resulting unbalanced vertical stess at the surface is equated to the acoustic pressure. Second- and third-order terms are retained in the surface-wave description (and fourth-order in the nonlinear interaction model). By further equating the viscous dissipation in the surface wave with the net upward acoustic energy flux, the surface-wave parameters are determined in terms of the acoustic-field parameters.
