针对居民区配电房噪声扰民问题，研制了一种新型复合微孔气液悬浮隔声材料，并对其声学性能及燃烧性能进行了测试，均能满足相关国家标准。利用该材料设计变压器专用隔声罩，并提出了配电房降噪改造方案，进行了现场试点试验。结果表明，本文设计的改造方案有效降低了变压器低频噪声，使配电房噪声由原来的56dB降至44dB，满足了《城市区域环境噪声标准》规定的标准限值。
針對居民區配電房譟聲擾民問題，研製瞭一種新型複閤微孔氣液懸浮隔聲材料，併對其聲學性能及燃燒性能進行瞭測試，均能滿足相關國傢標準。利用該材料設計變壓器專用隔聲罩，併提齣瞭配電房降譟改造方案，進行瞭現場試點試驗。結果錶明，本文設計的改造方案有效降低瞭變壓器低頻譟聲，使配電房譟聲由原來的56dB降至44dB，滿足瞭《城市區域環境譟聲標準》規定的標準限值。

This paperdeveloped a new composite microporous gas liquid suspension insulation material to solve residential power distribution room noise,and tested for its acoustic and burning properties,which both meet the relevant national standards.Designed transformer special acoustic enclosures with this material,and made a plan to reform distribution room, and conducted a field pilot test.The results show that the design of rehabilitation programs to reduce the transformer low-frequency noise is effective, distribution room noise from the original 56dB fell to 44dB, which meet the standard limits of ""Standard of Environmental Noise of Urban Area."".
