A good vibration isolator lowers the natural frequency of a system to below the excitation (or disturbing) frequency. Keeping these two frequencies "out of sync" greatly reduces the problems of vibration.
A good vibration damper takes mechanical energy out of the system.
Properly designed metal springs and rubber mounts can be good isolators but have almost no damping capability.
