Abstract
This paper proposes to reduce a heavy-weight impact noise of double floor. The magnetic levitated leg using the repulsion of permanent magnet has been developed to isolate the impact force from the double floor. In the experiments, construction method of the magnetic levitated legs is investigated from the displacement of static or impact load, and the floor impact noise. The experimental results show that the heavy-weight impact noise could be reduced about 10dB in range of 32-250Hz octave band. However, the displacement of static load was increased than the traditional rubber support legs.
