Recent time-of-flight measurements have been interpreted in terms of a force-constant model. We show that for phonon waves propagating along the ΓX direction, containing nearest neighbors, it is necessary to introduce a large softening of the lateral surface force constants (40%) in agreement with earlier calculations on the Ag(111) surface
