Comparison of the Measured and Simulated Results of the Dry Double Flooring of Heavy Weight Floor Impact Sound at the Reinforced Concrete Wall Construction Testing Device

Abstract

In this paper, we have examined the forecast of heavy-weight floor impact sound level in the housing using the Finite Element Method (FEM). Analysis object is a heavy-weight floor impact sound of dry double floor construction to the laboratory wall construction. 63Hz band analysis results is included in 65% (within ± 5dB) the difference between the measured and analysis value, the result was good correspondence. In the evaluation of the L-value, prediction of heavyweight floor impact sound of dry double floor using the FEM is a sufficient prediction accuracy.
