摘　　要：针对五面封闭的液压提升机硐室声场,采用统计能量分析(SEA)理论建立液压泵站硐室、墙体、门、主硐室声场模型,详细计算分析SEA模型的损耗因子、模态密度等相关参数,分析墙体和门的隔声降噪特性,预测液压提升机硐室和司机操作台噪声,对全面开展提升机井下硐室环境噪声控制具有一定作用。The sound field of hydraulic hoist chamber with five sides sealed is studied in this paper.The acoustic models of the pump station chamber,walls,doors and the main chamber are established by applying the statistical energy analysis（SEA） theory.The loss factors,modal density and other related parameters of the models are determined and analyzed.The sound insulation and noise reduction characteristics of the walls and the doors are analyzed.The noise of hydraulic hoist chamber and driver＇s console is predicted.This work has significance and guidance for the hydraulic hoist chamber＇s environmental noise control.
