Firstly, the noise characteristics of the flow between the drop and the chute were compared experimentally. As a result, it was certified that the chute fulfills the function of the countermeasure to the water noise for a certain condition.Nextly, the relations between the condition of the flow immediately below a undergate and the water noise were characterized by experiments. As a result, it was certified that the water noise don't happen if submerged factor S is more than 2.Lastly, the water noise of Sabo dam and so on were observed, and relations between the band of the frequency and the water noise were indicated experimentally.

首先，通过实验比较了水滴和溜槽之间的流动噪声特性。结果表明，在一定条件下，该溜槽能够满足水声对抗的功能，并通过实验研究了闸门下水流条件与水声的关系。结果表明，当淹没因子S大于2时，不会产生水噪声。最后，对沙坡坝等地的水噪声进行了观测，并从实验上指出了水声频带与水噪声的关系。
