This paper studies the mechanism generated from flow - noise in seawater pipeline, introduces controlling method of flow - noise, analyzes sound field characteristics of flow - noise in seawater pipeline system and the merits and demerits of measuring the flow - noise methods in and out of the pipeline. in our experiment, a test measuring device of seawater muffler is used in a measuring chamberlet to verify that a method of reverberation chamberlet is difficult to exactly measure the low frequency flow - noise in pipeline. at the same time the insertion lose of water muffler in the low frequency was measured by the measuring chamberlet method
本文分析了海水管路系統內流噪聲的產生機理，介紹了流噪聲的控制方法；分析了海水管路系統中流噪聲的聲場特性以及流噪聲管內、管外測量方法的優缺點；通過海水消聲器試驗測量臺架，利用測量小室驗證了混響箱法難以準確測量海水管路系統中的低頻流噪聲；用測量小室對水消聲器在低頻段的插入損失進行了測量。 -

摘要探討了圓盤型進氣消聲器對蝸殼振動和聲輻射的影響。 -
Through testing on muffler on a certain motor, the paper evaluates the static performance of sound transmission loss of the muffler
通過對某種發動機使用的消聲器進行測試，對消聲器的靜態傳聲損失性能作出評價。 -
When other sound sources are under further control, the air inlet may become the primary sound source. under this situation it is proposed to apply good intake mufflers. usually the intake muffler needs to combine with the air cleaner in an integrated design to meet requirements of air admission and cleaning as well as perform an effective control over the air inlet noise
而當其它聲源得到進一步控制后，進氣噪聲有可能成為主要聲源，這時需考慮採用性能良好的進氣消聲器，通常進氣消聲器要和空氣濾清器結合，進行一體化設計，既能滿足進氣和濾清方面的要求，又可使進氣噪聲得到有效的控制。 -
A gas flow in such a scenario will affect the sound field distribution, the sound speed and the sound propagation mode inside the muffler
此種狀態的氣流將會影響消聲器內部的聲場分佈、聲速、聲的傳播規律等，特別是氣流速度影響更大。
