When operator in various industrial working area is exposed to noise, the working efficiency may be influenced by the acoustic environment. This paper describes; (i) the design proposal for the acoustic environment in consideration with the quantitative analysis of the working efficiency, (ii) the result of experiment by the evaluation method of work load, human impression under office work regarding the relation between noise, working efficiency and human impression, (iii) the optimum evaluation methods with the aim of comfortable environment and improvement of the working efficiency.
