ABSTRACT:
A damper assembly for pianos is provided with at least two damper felt sections disposed to its damper head in such a manner to enable dual staged damping action, only the large amplitude components of string vibration being damped in the first stage, and the remainder of the string vibration being almost fully damped in the second stage. Stable damping effect on the string and minimized jumping of the damper felts are attained in particular in the bass range.
