The invention discloses a noise-reduction shock-absorption device which relates to the field of transformer auxiliary equipment. The noise-reduction shock-absorption device comprises an upper-layer outer shell and a lower-layer outer shell fastened with each other, wherein lower-layer shock-absorption devices, a shock-absorption support, a support frame and upper-layer shock-absorption devices aresequentially connected between the upper-layer outer shell and the lower-layer outer shell from bottom to top; the lengths of the shock-absorption support and the support frame are less than or equalto the length of the upper-layer outer shell; at least two lower-layer shock-absorption devices and at least two upper-layer shock-absorption devices are arranged; and the upper-layer shock-absorption devices and the upper-layer outer shell are in point contact fixing. The noise-reduction shock-absorption device provided by the invention solves the problem that a larger shock noise is produced ina building due to shock of a transformer, and has effects on reducing noise and absorbing shock for a working state of the transformer.
