To obtain the basic characteristics of the vibration in the building many vibration measurements were carried out to devise a simple prediction method of the structure borne sound. In this paper, vibration measurements of the three buildings were carried out to construct the analysis model to predict how vibration input into the foundation amplifies it in each floor of the building, and a multi-degree-of-freedom system to simulate these measurement results were proposed. In addition, although some measures method for the structure borne sound was devised and it has been in use, the Tuned Mass Damper (TMD) which used the vibration of balconies and corridors as an idea of structure borne sound reduction tuned in the desired frequency were devised, and the effect were confirmed by the simulation using the proposed analysis model.
