Abstract
An engine mounting buffer rod is constructed to constitute two suspended masses interconnected by elastomeric means to endow on the rod two resonance frequencies. The resonance frequencies are selected to span the vibrational range in which resonance noise is apt to occur in the vehicle cabin so that a first change in the phase of vibration passing through the buffer rod causes an interference with the vibration passing through the main engine mounting brackets to soften the mounting arrangement as a whole and absorb vibrations which would otherwise induce cabin resonance noise. The effect of the second resonance overlaps the first to prolong the softening effect until the second phase change induced thereby occurs.
