Abstract
In this paper, we study the predicted floor impact sound level by finite element method. At first, we study the influence of the partition on the slab vibration in addition to the impedance characteristic of the partition.Following this, the influence on the slab vibration characteristic is shown by the construction of the partition.In addition, it is shown that the model employed in this experiment is more effective than the board unit based on the impedance characteristic of the partition.Finally, the difference between the partition groundwork specification and the space size forces the examination of the influence on the vibration characteristic and the space sound pressure.Following this, it is shown that the influence of the sound radiation of the partition is minimal in the evaluation frequency of the floor impact sound insulation.
