Vibration damping and sound insulating device

Abstract

A vibration damping and sound insulating device installed on an installation object, includes: vibrators disposed at a prescribed spacing. Each of the vibrators includes: a cylindrical tubular member on the installation object; an elastic body supported by the cylindrical tubular member such that the elastic body traverses a hollow portion of the cylindrical tubular member along a direction orthogonal to an axis of the cylindrical tubular member; and a weight on the elastic body. The prescribed spacing is determined based on a half-end-length spacing of a wavelength of a bending wave generated in the installation object.
