Acoustical Analysis of Auditorium in National Educational Museum, West Java

Abstract

Abstract Besides being the place for evidence of past history and future history, the National Educational Museum in West Java also has audio visual room, for the visitor to learn about the museum more. Visitor ability to understand what is being said in the auditorium depends on the acoustics quality of the room. This study primarily talks about acoustics auditorium and find out if the acoustics in Auditorium of National Educational Museum is optimal for its function. The objective of this analysis is to determine the acoustics quality of the room in Auditorium of National Educational Museum. The simulation results with acoustic standards was carried out after conducting field observations and simulations using Ecotect v.5.50 software. After the simulation conducted it is known that there is some factors that makes this auditorium reverberation time not optimal such as sound-reflecting materials, floor and ceiling shape and elevation, and the number of occupants in the room. Which resulted in the speaker’s voice become less clear to the perceiver. Thus, to respond to the issue some materials can be change to sound-absorbing materials, and the ceiling shape can be made simpler to reduce the reverberation and echoes.
