  The surface waves in the visco-elastic media with the surface tension are
studied using the Voigt-Kelvin model of the visco-elasticity. It is shown that
the surface mode of oscillation does not exist in the parameter region where
the effect of surface tension is larger than that of the elastic stress at the
surface unless the viscous stress masks the elastic stress in the bulk. In the
region, the surface oscillation is suppressed and the oscillation beneath the
surface diffuses after the pulse goes into the bulk. The experimental relevance
of the present results is also discussed.
