Wide-band vibration damper

摘要

A vibration damper for damping sound propagating in solids includes vibration damping horn members connected through a damping material to a support point on the surface of the solid in such a manner that a tapering portion of the horn member contacts the solid through the damping material. The taper in a horn member, for example of circular cross section, is considered to be the curvature of the horn member away from a generatrix of the horn member. The damping factor of the connecting damping material is equal or substantially equal to the terminal impedance of the horn member.
