室内固定设备结构传播噪声的预防与减缓措施分析

An Analysis on the Prevention of Structural Propagation Noise from Indoor Stationary Equipment and Its Mitigation Measures

固定设备结构传播噪声是近年来城市建设发展中居民投诉较多的典型噪声污染类型。以上海市某居民住宅室内环境受结构传播噪声影响为例,分析出机械噪声和气体动力性噪声是2种主要的结构传播噪声。通过源强控制和传播途径控制措施可有效降低噪声的产生和扩散。指出各种降噪措施对于结构传声的有效性和适用性。

Recently, the structural propagation noise from indoor stationary equipment is one of typical issues frequently complained by residents. Taking the impact of structural propagation noise at indoor environment in residential quarters in Shanghai as a case, it was found that mechanical noise and aerodynamic noise are of major ones through structural propagation. The most effective ways to depress noise bringing about and spreading would be the measures for controlling the noise intensity and propagation roads. The effectiveness and applicability of various measures have been given for debasing the noise through structural propagation.
