Study of Livability of houses

目前人们对住宅宜居性的研究方法多种多样。定量地估计了人类对宜居性的敏感性。虽然出现了“病室综合症”和“VOC”等新问题，但影响居住环境的主要问题是室内热、声。在这两个问题中声音是很难减少的。在本研究中，我们估计了窗户打开和关闭状态下的响度差异。并开发了对重型地板撞击噪声降低5dB的主动噪声控制系统。在本研究中，估计了真实的损坏与外界人员想象的损坏之间的差异，并将损坏的木屋百分比视为正确值。然而，其他结构的百分比被认为更高。

Now livablility of houses are studied from various methods. The human sensitivity for the livability is estimated quantitatively. Although the new problem of "sick house syndrome" and "VOC" appears, The main problems for the livability are heat and sound in houses. In the two problems sound is difficult to reduce. In this research, we estimated the difference of loudness for open and close condition of window. And we developed the active noise control system to reduce 5dB for heavy weight floor impact noises.Also we studied the estimation of house damage by Hanshin-Awazi "earthquake. In this study, the difference between real damage and the imaginary damage by the outside people was estimated.The percentage of broken wooden houses was recognized to be correct values. However, the percentages of other constructions were thought to be more higher.
