Abstract: A sound-insulating curtain includes a sound-absorbing core formed by laminating porous sheets and films, is covered by covers, and sewn in an integrated manner. Even after being integrally laminated, adjacently laminated layers are not excessively restrained in places other than sewn areas, and therefore displacement and deformation between layers caused by sound pressure can be tolerated.
