  We investigate the response of the traversable wormholes to the external
perturbations through finding their characteristic frequencies and time-domain
profiles. The considered solution describes traversable wormholes between the
branes in the two brane Randall-Sundrum model and was previously found within
Einstein gravity with a conformally coupled scalar field. The evolution of
perturbations of a wormhole is similar to that of a black hole and represents
damped oscillations (ringing) at intermediately late times, which are
suppressed by power law tails (proportional to t^{-2} for monopole
perturbations) at asymptotically late times.
