We discuss surface scattering in terms of bidirectional reflectance distribution function. We formulate a boundary condition that in addition to diffuse and specular reflection has tilted diffuse reflection. We apply the boundary condition to calculate the transverse acoustic impedance of a normal-state Fermi liquid. Some additional results on the impedance in a slab geometry are presented.
