空化噪声是指在螺旋桨的周边附近产生涡流以及高声强的发射情况下，水流产生局部压力的降低，从而出现空化，当空化气泡破裂时,会产生脉冲式的噪声，即所谓“空化噪声”，它有连续谱。对于任何高速的舰船，发生空化现象后，空化往往是主要的噪声源。发射器表面会被腐蚀,引起声功率损失，指向性图变坏。
超声波清洗空化噪声 ultrasonic cleaning noise
Power Spectrum analysis is always used in spectrum analysis of cavitation noise. However, it is obviously unfit for research on the transient signal such as cavitation noise.
空化噪声的谱分析一般采用功率谱分析，而功率谱分析在研究空化噪声这种具有很强突变性的信号具有明显的缺陷。
