SOUND REDUCING SYSTEM, SOUND REDUCTION AMOUNT ADJUSTING METHOD, SOUND REDUCTION AMOUNT ESTIMATION METHOD, AND EQUILIBRIUM STATE DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sound reducing system that reduces sounds by absorbing the sounds by using sprayed water, and an estimation method for estimating the amount of sound reduction brought about by the sprayed water. ! SOLUTION: A sound reducing system 1 for reducing noises from a blast sound source 13 includes: a closing body 4; and a spray device 2. The closing body 4 is provided on a noise propagation path, and formed by being partitioned with partition materials 20a and 20b. The spray device 2 sprays water particulates into an internal space S of the closing body 4. ! COPYRIGHT: (C)2014,JPO&INPIT
