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

−A study of the prediction method of heavy weight floor impact sound of dry double floorings using the finite element method (part1)−

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 heavy-weight floor impact sound of dry double floor using the FEM is a sufficient prediction accuracy.
