ABSTRACT An adjustable or variable frequency vibration damper suitable for absorbing energy causing vibratory noise in automotive vehicles or industrial machinery, comprising an inertial weight of a mass suitable to be effective as a tuned energy absorber having at least one suitably placed aperture therethrough to receive a frictionally interfacing member of readily compressible elastomeric material secured only to the inertial weight, said elastomeric member provided with an aperture therethrough, said aperture having an axis substantially concentric to that of the aperture in the inertial mass; the elastomeric member bracketed by two cups spaced at opposite ends of the at least one aperture through the inertial weight, each cup substantially comprising an annular wall carrying a concentric flange at one end thereof proximate the elastomeric member and having an aperture therethrough, fastening means communicating through the aligned apertures in the cups and the elastomeric member adjustably securing the cups together to permit the cups to be adjustably moved towards one another compressing the elastomeric member, or away from one another decompressing the elastomeric member, the weight of the inertial mass being considerably greater than the elastomeric member, and, suitable fastening means for mounting the damper to only one vibrating mass whereby the said fastening means communicates between the only one vibrating mass and the elastomeric member.
