On the occasion converting office into apartment, the authors propose to improve performance for vertical vibration by jointing to up and down floor by vertical supports equipped viscous-elastic materials, and for sound insulation of floor for heavi-weight floor impact sound by floor framing supporting sleeper with viscous-elastic materials on beam. By vibration analysis, we confirmed these methods are effective as follows, vertical maximum response displacement decreases to about 55〜75 percent, floor response acceleration decreases on all frequency of 1/3 octave band by using vertical supports, and driving and transfer impedance level increase in the frequency range of heavy-weight floor impact sound.
