    • PURPOSE:To eliminate unpleasant sounds by measuring a solid low vibrating status quantity of a building generating from a track with sensors, comparing the information of the status quantity with a known characteristic of the building to output a control signal, and driving vibrators to vibrate reversedly the building. CONSTITUTION:Vibration sensors 3 are placed in a plurality of places in a building 1 drawing a railway track 2 in the inside of a construction, and vibration is converted into an electric signal. After that, the electric signal is inputted to a controller 6 such as a digital controller, etc., through an amplifier 4 and an A/D converter 5. Then, in the controller 6, an input signal is compared with the known characteristics of the building 1 such as a natural period of the building 1, attenuation vibration form, etc., and a feedback grain obtaining the optimal controlling force to reduce vibrations of the skeleton is calculated. A digital signal of the calculated gain is transmitted to vibrators 8 arranged in proper positions of the building 1 through the D/A converter, and the building 1 is vibrated reversedly.
