STUDY OF ACOUSTIC SYSTEM IN THE AUDITORIUM OF THE GERMAN CULTURAL CENTER (GOETHE-INSTITUT), CENTRAL JAKARTA

Abstract

The Goethe-Institut is a cultural institution from the Federal Republic of Germany with a global reach. The Goethe-Institut promotes knowledge of the German language abroad and maintains international cultural cooperation. Through information related to the cultural, social, and political life of their country, the Goethe-Institut conveys an overview of Germany. Its cultural and educational programs encourage intercultural dialogue and enable cultural engagement. One of the main facilities needed to accommodate and distribute creations in these fields is the auditorium. The acoustic system is an important aspect of an auditorium as it greatly affects the comfort of visitors. The purpose of this research is to determine the right shape of the room so that the sound energy can be evenly distributed, to find alternative acoustic materials suitable for an auditorium, and to develop interior elements (floors, walls, and ceilings) that can be applied to the interior of Goethe-Institut’s auditorium. This study uses the qualitative method. The research that has been done reveals that based on the acoustic design, the design of the Goethe-Institut auditorium is not yet optimal. The acoustic quality of the Goethe-Institut auditorium can be improved by using reflective materials on the ceiling and absorbent materials on the doors of the audience area, as well as absorbent materials on the floor, reflective materials on the ceiling, and absorbent and diffusing materials on the back wall of the stage area.
