jaue2019-009: Evaluation of Reverberation Time and Lighting Performance in the Student Room

Abstract

The student room as a place of education requires tranquility and comfort in the learning process. The primary 
functions of the student room are for learning, group learning, meetings, and various activities related to this where 
good speech communication is critical to a student’s academic achievement. To improve the effectivity and 
productivity of lecture activities, then this study was conducted at the Student Computer Lab (N160) of Graduate 
School of Information, Production and Systems, Waseda University, Hibikino, Kitakyushu, Japan. The study was 
based on the experience of authors in the use of existing classrooms in aspects of the auditory and visual 
environment. The method used is to make existing building models, measuring the condition of the room using 
formulas and software, and developing a comparison of modifications (after change) based on several modifications 
of the room materials. In this study, the reverberation time is calculated manually with the Sabine Formula while 
the DIALux evo software is used to assist in the design of artificial lighting systems and illuminance distribution. 
The result of the evaluation was then compared to the standard as a comparison and workable improvement to 
enhance the acoustic quality and lighting performance of the room.
