STUDY FOR REDUCTION OF THE FLOOR IMPACT SOUND LEVEL BY THE USE OF DAMPING MATERIALS : Part 1: Experimentation concerned with technology of the damping materials

Abstract

This paper shows several experimental results concerned with the utilization technology of damping materials. And the following conclusions were obtained. First, the acoustic and vibration characteristics of damping materials for building haven't been examined fully, and so the damping materials haven't come into wide use in building. Secondly, the experiment aimed at the acoustic and vibration characteristics of damping materials was able to confirm the effect of the damping materials.
