SOUND ABSORPTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a sound absorption structure capable of manufacturing a Helmholtz resonator with a simple configuration.SOLUTION: A sound absorption structure comprises: an acceptance member 10 fixed to a building frame 50 side; a resonator main unit material 20 fitted to the acceptance member 10; and small opening lids 30 fixed at both ends of the resonator main unit material 20. The resonator main unit material 20 has a substantially U-shaped cross-section. The small opening lids 30 cover both end openings of the resonator main unit material 20, and the acceptance member 10 is fitted to a longitudinal opening of the resonator main unit material 20 to form a Helmholtz resonator.
