机场周边既有住宅隔声改造后评估案例研究

A Case Study on the Completed Sound Insulation Transformation for the Existing Residence around the Airport

按照诊断性后评估的程序与方法,对某机场周边既有住宅隔声降噪工程进行了使用后评估。评估的内容包括社区的整体环境质量、改造后室内外声环境、居住舒适度、隔声门窗使用情况、改造后阳台的使用情况以及居民针对隔声改造工程的意见与建议等7个方面。通过24h噪声监测、居民问卷调查、入户访谈,以及技术座谈会等方式,得出了初步结论。综观各项评价标准,可知该住宅隔声改造工程的综合效果较好,住宅室内声环境较改造前有了明显的改善,且居民的居住舒适度得到了一定程度的提升。但是在阳台的使用便利性、隔声门窗开启设计、项目施工管理、隔声措施的系统性、飞机噪声的针对性以及适老性设计等方面仍存在一定的改进空间。
