摘　　要：为了研究试验器工作时对厂界噪声的影响,以某厂房为研究对象,提出厂界噪声的治理方案。通过现场排查、识别厂房噪声源,对噪声源进行噪声测量,分析得出各噪声源最大噪声。依据噪声源最大噪声值,开展噪声治理需求分析。按照需求分析结果,提出厂界噪声治理总体方案,详细介绍了各种隔声降噪设备的结构组成。利用仿真软件对厂界噪声治理方案进行数值模拟,仿真结果表明,通过噪声治理后,厂界噪声不超过60 dB,噪声排放指标满足国家环保标准Ⅱ类标准昼间要求。In order to study the influence of the tester on the noise at the plant boundary during operation,a plant was taken as the research object,and a control scheme of the noise at the plant boundary was proposed.Through on-site investigation and identification of plant noise sources,the noise source is measured,and the maximum noise value of each noise source is obtained.According to the maximum noise value of the noise source,the demand analysis of noise control is carried out,and the demand is converted into the design requirements and design indicators of sound insulation and noise reduction equipment,and the feasibility analysis is carried out.According to the results of demand analysis,the overall scheme of noise control is put forward,and the structure of various noise reduction equipment is introduced in detail.The simulation software is used to numerically simulate the noise control scheme at the plant boundary,and the simulation results show that the noise at the plant boundary does not exceed 60 dB(A)after the noise control,and the noise emission index meets the daytime requirements of the national environmental protection standard Class II.standard.
