Document Type and Number:
Japanese Patent JP2018087481
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound absorbing structure capable of absorbing sound corresponding to various frequency ranges without a loss of uniformity of design.SOLUTION: A sound absorbing room is configured which is provided with a resonator body member 20 having an approximately U-shaped opening attached so as to approach a panel material 40, and a partition wall part W which partitions an internal space formed of the panel material 40 and the resonator body member 20, at least one of the spaces partitioned by the partition wall part W functioning as a Helmholtz resonator.SELECTED DRAWING: Figure 3
