Abstract
It is an object of the present invention to provide a solid-borne sound reducing structure which is able to reduce solid-borne sound with a simple configuration, highly durable, and being less degraded.There is provided a solid-borne sound reducing structure (100) in which a surface plate part (1) including a gas ventilating part (1a) which allows gas to pass through along a thickness direction is disposed by means of an outer peripheral wall part (2) on a structure (200) that radiates noise while vibrating, so as to at least partially cover a surface (200a) of the structure (200). The surface plate part (1) is supported by the outer peripheral wall part (2) so as to be integrally vibrated with the surface (200a) of the structure (200). In addition, the outer peripheral wall part (2) supports the surface plate part (1) in such a manner that an internal gas chamber is formed between the surface (200a) of the structure (200) and the surface plate part (1).
