As a new countermeasure to the interior noise of the railway vehicle, a development for a noise control system with piezoelectric material has been advanced. This paper describes availability verification test about the system in the railway vehicle. For the test of the noise reduction effect in running vehicle, we manufactured the noise control system sets for a deck of the Shinkansen, and assessed the noise reduction effect in stationary test. Numerical analysis was carried out about the noise change distribution in the deck at a target frequency when the noise control system applied on the outer-side gable wall. Furthermore, the noise control systems are actually installed on the outer-side gable wall in a deck of the Shinkansen vehicle, the interior noise of the deck suppressed maximum 4dB in control frequency range, and the result demonstrates the availability of the system to the railway vehicle.
