FLOOR SOUNDPROOF EXPERIENCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a floor soundproof experiencing device which makes it possible to experience the respective soundproof performance of floor structures varying in construction. SOLUTION: An experiencing hut 1 is partitioned by a partition material 14 to an experiencing room 12 on a lower side and a noise generating space 13 on an upper side. This partition material 14 is partly formed of an ALC floor structure and partly formed of an existing wooden floor structure. The device is provided with a falling object transporting machine 2 for discretely dropping a falling object 3 to the respective floor structures. This falling object transporting machine 2 drops the falling object 3 to the floor structure 15 of the existing wooden floor structure, then recovers the falling object 3 and drops the falling object 3 to the floor structure 16 of the ALC floor structure.
