摘要
目前,冷却塔噪声评价所采用的指标是A声级。而由于A声级并不能全面的反应冷却塔噪声污染的特性。本文通过对冷却塔噪声污染案例进行频谱监测,探讨了频谱分析方法对评价冷却塔噪声污染特性的可行性。
At present, the cooling tower noise the evaluation index is the equivalent continuous sound level A. But because of the char- acteristics of the equivalent continuous sound level A and can not fully reactor cooling tower noise pollution. Through spectrum monitoring of cooling tower noise case, probes into the feasibility of frequency spectrum analysis method for evaluation of cooling tower noise characteristics.
