摘要
目的探讨某噪声车间内交接控制室隔声、吸声等降低噪声改造方法。方法于2021年12月,通过对某噪声车间交接控制室进行职业卫生学调查及现场检测,分析噪声超标原因,提出降低噪声的改造设计方案并进行效果分析。结果噪声车间交接控制室改造前峰值频带噪声强度为112.8dB(A),峰值频率位于1000Hz。改造后理论计算控制值为61.0dB(A),实测噪声强度为59.8dB(A)。结论降低噪声改造后交接控制室噪声强度降低,符合GBZ1-2010《工业企业设计卫生标准》中控制室接触限值要求,对噪声治理工程具有参考意义。
Objective To explore the sound insulation,sound absorption and other noise reduction transformation methods in a noise workshop handover control room.Methods In December 2021,through the occupational health investigation and on-site testing of the handover control room of a noise workshop,the causes of excessive noise were analyzed,and the transformation design scheme to reduce noise was proposed and the effect was analyzed.Results Before the transformation,the peak frequency band noise intensity of the noise workshop handover control room was 112.8 dB(A),and the peak frequency was 1000 Hz.After noise reduction,the theoretical calculated control value was 61.0 dB(A),and the measured noise intensity was 59.8 dB(A).Conclusion The noise intensity of the handover control room is reduced after noise reduction,which is in line with the contact limit requirements of the control room in GBZ 1-2010"Hygienic Standards for the Design of Industrial Enterprises",and has reference significance for noise control engineering.
