Abstract
A sound-absorbing structure body according to the present invention comprises a ridge-groove board (11) formed with a large number of ridges and grooves, a closing board (15) joined to the ridge-groove board so as to close one side of the ridge-groove board and thereby form a hollow portion (13), a partition board (21) for partitioning the hollow portion (13) into two or more partitioned spaces (22a, 22b), and two or more holes (25a, 25b) opened in the ridge-groove board so as to bring into communication with each of the two or more partitioned spaces (22a, 22b).
