燃机进风口噪声声压级高，频带宽，大部分采取高位布置，并且由于进气量的限制，属于燃气电厂众多声源中较难治理的噪声之一。我公司在燃气电厂噪声治理的多年实践中，先后成功设计开发出“隔吸声屏障”、“隔吸声屏障+进风消声器”、“燃机进风口进风消声器”三种噪声治理措施，有效控制了燃机进风口的噪声。主要对不同的现场条件下，燃机进风口采取的不同的降噪措施进行详细阐述。
燃機進風口譟聲聲壓級高，頻帶寬，大部分採取高位佈置，併且由于進氣量的限製，屬于燃氣電廠衆多聲源中較難治理的譟聲之一。我公司在燃氣電廠譟聲治理的多年實踐中，先後成功設計開髮齣“隔吸聲屏障”、“隔吸聲屏障+進風消聲器”、“燃機進風口進風消聲器”三種譟聲治理措施，有效控製瞭燃機進風口的譟聲。主要對不同的現場條件下，燃機進風口採取的不同的降譟措施進行詳細闡述。

sound pressure level of Gas turbine inlet noise is high, wide band, high most of the power plant is layout arrangement, and as a result of the limitation of air inflow , belong to one of the more difficult noise to control in gas power plant noise. in the practice of the gas power plant for many years, our company has successfully designed“acoustic insulation barrier”,“acoustic insulation barrier+ intake muffler”,“the gas turbine inlet air muffler”three kinds of noise control measures, effectively reduce the noise of the gas turbine inlet noise. this article mainly discusses three different kinds of noise reduction measures taken by the gas turbine inlet in detail in the different site conditions.
