降低锅炉房噪声的措施

Measures for Reducing Boiler Room Noise

介绍了噪声的隔声机理,噪声叠加、点声源随传播距离增加产生的声压级衰减值、面声源随传播距离增加产生的声压级衰减值的计算方法。探讨了降低城市集中供热锅炉房噪声的措施,认为封闭隔声措施效果较明显。

Sound insulation mechanism for noise and calculation methods of noise superimposition, sound pressure level attenuation values of point sound source and surface sound source with increase of propagation distance are introduced. Measures for reducing noise from urban centralized heat supply boiler room are discussed, and it is concluded that the closed sound insulation effect is more obvious.
