Abstract
The purpose of this research is to reduce the floor impulse noise due to heavy-weight impact source. The supporting leg with magnetic damper is designed to isolate the impact force from the double floor by magnetic surfacing. In the experiment, the performance of supporting leg with magnetic damper is evaluated from the static load, the impact load, and the floor impulse noise. The experimental results show that the supporting leg with magnetic damper is effective to reduce the floor impulse noise due to heavy-weight impact source.
