非稳态噪声是指在观察时间内，采用声级计“慢挡”动态特性测量时，声级波动≥3dB的噪声。
同时非稳态噪声听力损伤比稳态噪声严重。
Meanwhile, hearing loss caused by unsteady noise is more serious than that caused by steady noise.
目的提高非稳态噪声性耳聋发病率预测精度。
Objective To improve the forecasting precision of the incidence rate of deafness induced by instable state noise.
因此得出结论：①非稳态噪声可以对动物行为产生影响，并随着噪声暴露时间的延长而增强；
The following conclusions were:first, non steady state noise had great influence on animal behavior, and the longer the exposure was, the greater the influence became.
