Conventional acoustic structures that absorb and reflect underwater sound have a specific structure, such as the plate-like structure made of a rubber elastic body with a cavity, which is proposed in Japanese Patent Publication No. 53-3242. Those that exhibited certain sound absorption characteristics were common. Therefore, in conventional underwater acoustic structures, the shape and structure of the structural materials of the underwater acoustic structure are determined by the structure corresponding to the installation location and type of sound, and the required sound absorption characteristics. It can no longer be used for other purposes. Also,
Many of the molded rubber sheets used as the sound absorbing materials that make up the underwater acoustic structures are relatively large in shape, making installation cumbersome, and molding molds must be individually designed and manufactured depending on the installation location and required sound absorption characteristics. It was necessary to do so, and the cost had to be high.

In the embodiment, the molded rubber sound absorbing unit 1
is housed in a sheet-like bag 5 to form an underwater acoustic structure O. By installing the underwater acoustic structure O of the sheet-like bag 5 on the wall surface of a swimming pool, for example, using a rope or weight, it can be made into an underwater acoustic structure that can prevent sound reflection from the wall surface. . When the underwater acoustic structure is no longer needed, it can be easily removed and used for other purposes.
