SOUND INSULATION SHEET MEMBER AND SOUND INSULATION STRUCTURE USING SAME
An object of the present invention is to provide a sound insulating sheet member that has high sound-insulating performance which exceeds mass law while being relatively light weight, that is highly flexible in design, excellent in versatility, and easy to manufacture so that productivity and economic efficiency can be improved, and a sound insulating structural body or the like using the same. The object thereof is achieved by using a sound insulating sheet member comprising at least a sheet having rubber elasticity and a plurality of resonant portions, wherein the resonant portions are provided in contact with a sheet surface of the sheet, each of the resonant portions including a base part and a weight part, and the weight part being supported by the base part and having a larger mass than the base part.
