| 摘 要： | 通过对350Mw燃气-蒸汽联合循环发电机组厂房内各个机岛以及辅助设备的现场噪声测量，分析了厂房内的主要噪声源及其频谱特征。根据测量结果计算了各个机岛噪声的声功率和厂房内工作面的声压分布，验证表明计算结果与实测结果吻合较好。根据主要噪声源的频谱特性探讨了降低厂房噪声声压的吸声隔声措施。

| Abstract: | In according to the noise measure inside the power plant of 350 MW gas-steam combined cycled generator,the main sources of the noise and its spectrum have been analyzed.Based on these measures,the sound power levels of various sound sources and the space distribution of sound pressure level which have been calculated in the paper tallied with the results of measure very well.Furthermore,some measures such as acoustic absorption and sound insulation were adopted aiming at reducing the frequency that dominate... |
