Evaluation of Reverberation Time in the Auditorium: Case of Assembly Hall of Engineering Faculty, Universitas Sebelas Maret

摘要

This research was conducted at the Assembly Hall or auditorium of Engineering Faculty UNS. This study aims to see the acoustic comfort and how to improve it by modifying the room material. The method chosen is the method with the least amount of modification. The method applied was measuring the room condition using laser distance meter and sound level meter, taking notes on the characteristic of the material used, and developing a simulation based on several modifications of the room materials. The result of the simulation was then compared to the standard of reverberation time. The study concludes (1) the acoustic condition in the room is indeed not meeting the standard to ensure users comfort, (2) the reverberation time is better when additional plasterboard ceiling is built. The simulation in this study was done through the help of Ecotect 2011.
