ABSTRACT:
A tunable damper for a torque transferring assembly having a tubular shaft including an inner surface defining an elongated cavity includes an input channeling portion and an output channeling portion, wherein each channeling portion is formed from a first predetermined foam material having a first density and a diameter sufficient for providing a resilient bias force against the inner surface of the tubular shaft. The tunable damper further includes at least one absorber formed from a second predetermined foam material having a second density different from the first predetermined foam material and first density, respectively. The at least one absorber is positioned between the input and output channeling portions for attenuating a first predetermined range of frequencies of noise produced or transmitted by the torque transferring assembly.
