Study on subjective annoyance and control method of indoor low-level and low-frequency noise and it's control(室内窄频带低频噪声烦恼度与治理对策研究)
低声级噪声对人们产生的影响目前尚未引起足够的重视,针对住宅楼底层箱式变压器引起的室内结构声污染,采用模糊数学原理进行了噪声烦恼度研究,发现在低频低噪声环境下(等效连续A声级<35dB)仍能引起较高的烦恼概率,且噪声大小与噪声烦恼度仍存在着较好的关联关系;对于同一中心声级的噪声,室内噪声烦恼概率的改变主要是由于室内噪声频谱特性改变所致;在低噪声级环境下,小幅度增强中高频噪声,利用噪声的掩蔽效应,可降低噪声烦恼.这为改变工作或生活场所室内声环境质量提供了一个新的思路.在声学分析的基础上,提出了以隔振为主防治对策,获得理想效果....
