SOLID-BORNE SOUND REDUCTION STRUCTURE

摘要

A simple solid-borne sound reduction structure for reducing solid-borne sound has a high durability and hardly degrading. A solid-borne sound reduction structure (100) comprises a structural body (200) radiating noise, a surface plate part (1) covering at least a part of the surface (200a) of the structural body (200) and having a gas-ventilating part (1a) capable of passing gas in the direction of the thickness of thereof, and an outer peripheral wall surface part (2) for securing the surface plate part (1) to the structural body (200). The surface plate part (1) is so supported as to vibrate with the surface (200a) of the structural body (200) in one body. The outer peripheral wall surface part (2) supports the surface plate part (1) so as to define an inner gas chamber between the surface (200a) of the structural body (200) and the surface plate part (1).
