정보화 시청각 강의실의 음환경 성능에 관한 연구 = A Study on the Sound Environmental Performance in Multimedia Lecture Rooms

다국어 초록 (Multilingual Abstract)

Noise is the most serious of complaints concerning buildings Multimedia lecture rooms can exhibit a drop m the quality of sound environmental performance because there are many kinds of machines and they make an abundance of noise. In this study we will measure the noise level of the equipment in multimedia lecture rooms such as PC, OHP, scanner, printer and will evaluate indoor sound environmental performance that ha:, been influenced by the noise of multimedia lecture room machines Sound environmental performance can be measured by analyzing noise level, reverberation time and sound insulation performance The results of analysis on the sound environmental performance m a multimedia lecture room will show the need to decrease the noise level of existing machines and future machines in multimedia lecture rooms and the need to increase the sound absorption coefficient of surface in multimedia lecture rooms
