Abstract
Reading room in the university is one of necessary facilities that university student must use. It is, therefore, very important to make reading room comfortable acoustically not only to minimize the annoyance to the users but also to provide efficiency in studying. Present study aims to investigate the current situation of reading room in terms of acoustics and moreover to find out the relationship between the indoor noise and users' satisfaction through questionnaire survey. As a result, the indoor noise level is quite higher than the 1st grade, 35 dB(A), that the Ministry of land, transport and maritime affairs suggests as certificate regulation for environment friendly building and there were lots of noise sources that can provoke users in studying or concentrating. Questionnaire survey illustrates that the sound when opening and closing door, and airborne sound from outdoor transmitted through window are most annoying, which affected users' dissatisfaction.
