摘 要:对石家庄、北京10个住宅小区居室声环境历时三年的研究表明:除临街住宅外,小区居室在夜间基本上满足睡眠环境的要求,在6:00~8:00和19:00~22:00时段各出现一个声级高峰;1993年较1983年的居室昼夜等效声级提高4.4dB(A);居民烦恼度和睡眠干扰率均与噪声级有很高的相关系数;处于吵闹环境临街住宅居民的心理症状出现率和神经衰弱症状出现率均高于小区组。Based on three years, we studied on the housing accoustical environment of ten housing estates in Beijing and Shijiazhuang. And this paper explored that the housing estate mainly satisfied needs of sleeping environment in night except those over looking street.It seperately a peak of sound level in period 6: 00~8 : 00 and 19: 00~22: 00.The day-night average sound level indoor was riser 4. 4dB (A)in 1993 than that in 1983. The annoyance and the sleeping interference ratio of the resident both had very high correlation coefficeent with the sound level. The positive ratio of the psychology and neurasthenia symptoms of resident in the noisy environment were both higher than that in housing estate group. Finally,it discussed the countermeasure of the noise controled in the district.
