Study On The Influence And Evaluation Of Acoustic Environment In Open Plan Office From The Perspective Of Health

With modern urban life becoming more and more efficient and efficient,people in the workplace are more likely to have psychological consumption,work efficiency decline,negative emotions and other phenomena."Healthy building" and occupational health perspective put forward new requirements on the built environment,so the environmental health of the workplace deserves special attention.Among them,sound environment is a component of the quality of healthy environment,which is crucial to create a healthy,comfortable and efficient office environment and maintain the physical and mental health of users.Open office space is more and more widely used for promoting cooperation,communication,feedback and knowledge sharing among employees.The special problems of acoustic environment brought by space openness have become the focus of attention of researchers.In 2012,the international standard for measuring the acoustic performance of open office space was issued,which realized the quantitative description of the acoustic performance quality of space,and triggered continuous and in-depth research in the academic circle.However,there are few systematic studies and reviews on the impact of acoustic environment on users in open office space from the perspective of healthy environment,and there is no perfect evaluation strategy.This paper takes the healthy environment as the perspective,pays attention to the physical and mental comfort and work efficiency of office staff as the starting point,and takes the open office space as the research object.Through literature research and theoretical deduction,the relationship between acoustic performance,sound source,sound environment and users is clarified,the content of acoustic environment quality assessment of open office space is clarified,and the research content and overall framework are proposed.Through the study of healthy building and occupational health related regulations,the perspective of health was analyzed.Based on the perspective of health,the spatial characteristics of open office space were investigated,and the subjective acoustic environment perception experience of open office staff was investigated to determine the acoustic environment problems and influencing factors.Based on the in-depth analysis of 117 domestic and foreign literatures related to acoustic environment,this paper clarifies the influence of acoustic environment on users’ emotional psychology and cognitive performance and the value of irrelevant speech in the study of acoustic environment.In addition,aiming at the main influencing factor--irrelevant speech,this paper combined with eye movement tracking technology to conduct cognitive experimental research on the Chinese context of the subjects in the simulated open office space,and explored the influence of irrelevant speech on the user’s cognitive performance and cognitive load from the aspects of "task performance" and "eye movement indicators".The acoustic performance and parameters of an open office space are defined through the sorting of acoustic environment specifications,and an open office space is selected for acoustic performance measurement.Finally,the measurement results are combined with 125 groups of performance parameter distribution in domestic and foreign literatures,the transverse comparison of existing relevant evaluation criteria and the subjective evaluation of users to comprehensively evaluate the acoustic environment.On this basis,the influence of acoustic environment is summarized and the strategies for assessing acoustic environment are proposed.According to the evaluation results,the design factors that influence the subjective and objective evaluation are summarized,and Suggestions for acoustic environment design are put forward.The main innovation of this study is to introduce a health perspective,to provide a new perspective for the study of the acoustic environment of open office space,and carry out corresponding theoretical analysis;The acoustic performance of an open office space was measured,and the acoustic environment quality of the space was evaluated by combining subjective and objective methods,so as to provide a basic quantitative basis for the improvement of the acoustic environment quality.The spatial design factors that influence the subjective and objective evaluation of acoustic environment are summarized to provide direction for the optimization of acoustic environment quality.
