PROBLEM TO BE SOLVED: To solve the problems in which, in a conventional sound absorption structure, a sound absorption effect is low, a large installation space is required and the degree of freedom of installation is low.SOLUTION: In a sound absorption structure 1, a sound absorption body is configured by: a bottomed cylindrical body 2 in which a hollow part 2a is slender; a sound absorption material 3 provided on one end side opening of the cylindrical body; and gap maintaining means for providing a required gap between the one end side opening end surface of the cylindrical body and a surface 4 of a room structure. The sound absorption body is arranged so that an axis a in a longitudinal direction of the hollow part is orthogonal to the surface 4 of the room structure, and a gap 5 is provided and disposed by the gap maintaining means between the end surface of the one end side opening 2c of the cylindrical body and the surface 4 of the room structure. |
