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.
