Abstract
This paper describes our proposal concerning the quantitative evaluation process to the acoustic environment, working efficiency and human impression for various industrial working areas based on the following analysis. (1)WWL score can be evaluated by NASA-TLX. (2)WWL score is changed by the condition of acoustic environment. (3)Action pattern of human has a relation with WWL score for mental and physical demand. (4)Working speed depends on WWL score. (5)Relation between the working speed and WWL score has a difference by action pattern. (6)Durability of working can be judged based on the result of evaluation for human impression.
