STUDY FOR REDUCTION OF THE FLOOR IMPACT SOUND LEVEL BY USING OF THE DAMPING MATERIALS : Part 4: Study of the damping characteristic making use of the Concrete Slab

Abstract

This paper describes several experimental results of the damping characteristic making use of the Concrete Slab. The flowing conclusions have been obtained. First, the damping effect contributes for the vibration reduction, same as the result of the Concrete Beam. Second, in the range of this experiment, the loss factor of the system does not depend on the change of the room temperature. Last, there is correlation in the effect of the vibration reduction and the sound radiation from the Concrete Slab.
