摘要
本文对柴油机水下排气噪声的规律性进行了实验研究.指出了柴油机水下排气噪声的发生过程,测试了多种消声模型的降噪效果.
The law and the production process of underwater exhaust noise from a diesel engine have been investigated experimentally, the measurement of the noise reduction effectiveness of many kinds of preproduction muffler models has also been made.
