This paper deals with the reduction of vibration and noise of a C-frame turret punch press of double-wall structure. The experiments were conducted varying the wall gap, thickness of outer panel and damping material filling the wall gap. From the experiments, it is found that the reduction rate of the sound pressure level is not expected to be large when the wall gap is larger than 4 times the thickness of the side panel, and becomes small when the outer panel is thinner than the inner panel. As for the damping material, sand is superior to cement concrete. The reduction of the sound pressure level of about 11 dB was achieved over a wide frequency range. In addition, the effectiveness of an impact mass damper integrated with the double-wall structure model is investigated.
