It is hard to reduce the noise trasmitted through the internal panel of the railway vehicle by any existing active control methods, which are necessay to identify the vibration-modes of target structure, because the vibration characteristics of the interior panel changes while running. We propose a new noise control system that the noise insulation panels with piezoelectric material arrange. The system enables the noise transmitted through the target plate to reduce by suppressing the vibration of the noise insulation panels with a simple analog control circuit. In this paper, after the equivalent mechanical models for a number of the piezoelectric material are shown, we demonstrate the analytical and experimental results about the control effects of the noise insulation panel and the noise transmitted through a target plate by the control system without identification to the vibration or transmitted noise characteristics of the target plate.
