摘　　要：通过对混凝土集中搅拌站固定噪声源与流动噪声源的测量,分析了主要噪声设备及其对厂界噪声的影响,提出了主厂房内局部隔声、地面流动声源屏障隔声等综合性噪声控制措施。实践证明,治理后厂界噪声基本达到了昼间60dB(A)、夜间50dB(A)的国家2类环境噪声功能区要求,取得了良好的环境工程效果。This paper, with measuring stationary noise source and moving noise source for a premixed concrete plant, analyzed the major noise equipment and its influence on the noise environment of factory boundary, put forward the noise control method for the local sound insulation of main workshop and for the long acoustic insulation wall of ground moving noise source. The result of noise con- trol showed that the noise level of factory boundary has basically reached the second criterion of national environmental noise function requirement, i.e. 60 dB（A） in daytime and 50 dB（A） at night, and that a good project effect has be gotten.
