PSYCHOACOUSTICAL EVALUATION OF FLOOR IMPACT SOUNDS FROM A CONCRETE SLAB WITH DAMPING MATERIALS ATTACHED : Study for reduction of the floor impact sound level by using of the damping materials Part 6(Environmental Engineering)

Abstract

We have conducted the floor impact tests in order to reduce floor impact sound pressure levels by attaching damping materials to concrete floor slabs. Using psychoacoustical analysis to evaluate the floor impact sounds, we got the results indicated that psychoacoustics quantities could be used for evaluating the effect of damping materials on the floor impact sounds and generally could be used as indexes for improving floor impact sound insulating performance of buildings and houses.
