With economic development, the noise generated by pipe networks in the gas station in emerging urbans has increasingly serious impact on people's life and work. In this paper, the noise generation mechanism was studied by Lighthill acoustic analogy, Curle theory, FW-H theory and Powell-Howe theory. Based on these theories, preliminary understanding and mastery of noise analysis software were realized. Then starting from the actual production, common effective noise canceling and reducing measures were put forward.%随着经济的収展，新兴城镇“怀抱”中的输气场站管网所产生的噪声已日益严重地影响到了人们的生活工作。本文对流噪声产生机理：Lighthill声比理论、Curle理论、FW-H理论和Powell-Howe理论迚行研究。在理论基础上，对噪声的分析软件有了初步的认识和掌握，且从实际生产出収提出了较为有效的常用防噪、降噪措施。
