A study on the physiological and psychological influence for the resident by life noise and its application to housing performance

调查了生活噪声对居民的生理和心理影响。人体总是受到附近产生的生活噪声的影响。因此，在24小时内，测量了人附近生活噪声的声压级（SPL）和等效噪声级（Leq），并对噪声进行了评价。采用五步评价法对噪声进行了三种评价。并测量噪声暴露时间和声压级。获得了一整天的最大声压级（100 ± 110（dBA））和24小时的Leq（60 ± 80（dBA））。生活行为期间的平均噪声水平可以如下所示：睡觉43（dBA）、用餐69（dBA）、烹饪69（dBA）、看电视66（dBA）、阅读61（dBA）、步行64（dBA）。许多受试者认为大于Leq 75（dBA）的噪声为“大响度”，小于Leq 40（dBA）的噪声为“小响度”。“当一个人想学习的时候，他会对相对较小的噪音产生一点不愉快的想法。在公寓中调查了室内噪音发生的次数，噪音的种类和居民对不愉快声音的指示次数。通过研究发现，生活噪声中最需要早期解决的是结构声，如地板撞击噪声和排水噪声。住房绩效在许多国家逐渐显现。但是，由于各国生活方式的不同，在表演项目上也存在一定的差异。在日本，为了获得舒适安静的房间，我们不得不在房间中引入绝对声级评价。

The physiological and psychological influence for the resident by life noise was investigated. The human body is always influenced by life noise which is born nearby. So, the noise levels ( SPL and Equivalent noise level (Leq)) of life noise near human subjects were measured during 24 hours with life behaviors, and the evaluation about noise. Three kinds of evaluation about noise were done by five-step. And the noise exposure time and SPL were also measured. The maximum SPL( 100〜110(dBA)) for a whole day, and the 24 hours Leq( 60〜80(dBA)) were obtained. The average noise level during life behaviors can be shown as follows ; sleeping 43(dBA), dining 69(dBA), cooking 69(dBA), TV watching 66(dBA), reading 61(dBA), walking 64(dBA). Many subjects evaluate that the noise more than Leq 75(dBA) is "large loudness" and the noise less than Leq 40 (dBA) is "small loudness." When one wants to study, he thinks with the unpleasantness a little for relatively small noise.The number of indoor noise occurrence, the kinds of noise and the number of indication of unpleasant sound by resident were investigated in the condominium. From this research, it was found that the most of life noises to solve early are the structure-borne sound like floor impact noise and drainage noise. The housing performance is shown in many countries gradually. But, there is some difference of performance items, because of the difference of life style for each country. In Japan, we have to introduce the absolute sound level evaluation in the room to obtained the comfortable quiet room.
