结构传声测量实例分析

固定设备结构传播噪声是近年来城市建设发展中出现的典型噪声污染类型之一。以沈阳某居民住宅室内环境受结构传播噪声影响为例,采用现场实测的方法,探讨分析固定设备结构传声测量过程中点位布设、现场测量及背景噪声修正等技术环节的不确定因素,对提高低频带噪声、背景噪声等测量结果的客观准确具有重要意义。

In recent years,fixed equipment structure transmission noise is one of the typical types of noise pollution in urban construction and development. The article study on a residential indoor environment in Shenyang is influenced by fixed equipment structure-borne noise,use the actual field measurement methods,discussed the uncertainty factors,such as point layout,field measuring technology and the background noise correction in the process of fixed equipment structure noise measuring,it's of a significance to improve the objectivity and accuracy of measurement results for the low frequency noise and background noise measurement.
