In this research, firstly, the lighting and sound environments of cafe were investigated. Next, behaviors involving "Chatting with a friend" and "Consulting about a course with a teacher" were investigated, and an experiment to find a volume suitable for the above behaviors under two kinds of lighting environment was done in the laboratory. The results of the experiment were as follows. 1. The suitable sound level was higher for "Consulting about the course with a teacher" behavior than "Chatting with a friend" behavior, and the individual variation of the former was more remarkable. 2. Significant influences of behaviors and types of sound were found on the suitable and permissible sound levels, however the influence of interior brightness was not found. 3. The suitable sound level for "Chatting with a friend" behavior exceeded the permissible sound level for "Consulting about the course with a teacher" behavior, varying according to the brightness and the type of sound, so it has been determined that it is difficult to set suitable sound levels for both behaviors.
