Zusammenfassung:	The utility model relates to a sound-absorbing material for improving a sound isolation and absorption effect. The utility model discloses a sound isolating and absorbing board comprising a top-layer board, a bottom-layer board, and a sound-eliminating material between the top-layer board and the bottom-layer board. The top-layer board and the bottom-layer board are connected through a keel. A cavity formed by the top-layer board, the bottom-layer board, and the keel is filled with the sound-eliminating material. The sound-eliminating material is a sound-absorbing cotton layer. The surface of the top-layer board is provided with sound-absorbing holes. The top surface of the top-layer board is provided with a plurality of shielding plates covering the sound-absorbing holes. The sound isolating and absorbing board has dustproof and waterproof functions, a good sound-absorbing property, and a sound-absorbing coefficient greater than 0.98, and is easy to manufacture, transport, and assemble, and convenient to install.
