Abstract
Rotational translation of an inertial mass rotor is used for providing damping of low frequency noise and vibration. An axial component is mounted so as to translate axial movement of an inertial linearly-displaceable member to rotational movement of an inertial mass rotor. The translation to rotational movement of the inertial mass rotor provides inertial amplification in the form of translational-rotational coupling. This enables the construction of a compact assembly, which allows light ultra-low frequency resonances to be concentrated, and which absorbs such low frequency noise energy.
