A vibration dampening system comprises a beam 28 which has an unsupported length and is affixed to a supporting structure 12. The supporting structure 12 is subject to vibrations which may be transmitted to the beam 28. A sheath 42 is rigidly mounted to the supporting structure 12. The sheath 42 substantially encloses a portion of the beam 28 and is spaced from the beam 28. An elastomeric dampener 46 is disposed between the beam 28 and the sheath 42. The elastomeric dampener 46 and the sheath 42 dampen vibrations of the beam 28.
