本文认为噪声是一种声信息，因此，运用信息理论建立起了一种新的环境噪声评价量模式──平均有效信息量．通过实际应用，表明其能较好地反映环境噪声水平．
In this paper, noise is considered as a kind of acoustic information. Therefore, the use of information theory has established a new model of environmental noise assessment - the average effective information. Through practical application, it shows that it can better reflect the environmental noise level.
