摘　　要：开放式办公室的声环境对工作人员的舒适度和工作效率有重要影响。开放式办公室声环境的影响因素较多,天花板材料、地板材料、挡板高度和背景噪声等因素会影响开放式办公室的声环境质量。本文基于Odeon建筑声学模拟软件,建立了开放式办公室声环境模拟模型,应用该模型可以针对开放式办公室声环境的参数语音空间衰减率D_(2,S)、距离声源4米处A计权语音声压级L_(p,A,S,4m)、分心距离r_(D)、私密距离rP和平均A计权背景噪声级L_(p,A,B)进行模拟计算。然后通过5个开放式办公室的实地测量并将实测数据和模拟结果对比,验证了该模型的有效性。最后基于该模型,本文对开放式办公室声环境的影响因素进行研究,分析了开放式办公室天花板材料、地板材料、挡板高度和背景噪声对其声环境的影响。本文所提模型和影响因素研究可以为开放式办公室声环境的优化设计提供参考。The sound environment of open-plan offices has a major impact on the comfort and efficiency of staff.There are many factors affecting the acoustic environment of open-plan offices,such as ceiling materials,floor materials,screen height and background noise.Based on Odeon building acoustic simulation software,this paper established a simulation model open-plan for office acoustic environment,and used the model to simulate and calculate the parameters of the open-plan office acoustic environment:spatial decay rate of speech D_(2,S),Aweighted speech level at 4 m distance L_(p,A,s,4m),distraction distance rD,privacy distance r_(P) and average Aweighted background noise level L_(p,A,B).The effectiveness of the model was then verified by the field measurement of five open-plan offices and the comparison between the measured data and the simulation results.Through this model,this paper further studied the influencing factors for the acoustic environment of open-plan offices,and analyzed the effects of ceiling materials,floor materials,screen height and background noise on the acoustic environment of the open-plan offices.The model built and influencing factors proposed in this paper can provide reference for the optimal design of open-plan office acoustic environment.
