Abstract
This paper describes the development of passive reduction of heavy-weight floor impact sounds by tuned mass dampers set at ceiling. Experiment was carried out with ceiling of the specification of general multiple dwelling houses. By using the tuned mass dampers composed of a viscoelastic body and a 50mm steel cube, the vibration acceleration level of the ceiling was decreased by 12dB. As a result, heavy-weight floor impact sounds level was decreased by 4-5dB.
