Comparison of Acoustic Characteristic among Electronic, Human-Played and Robot-Played Demung

Abstract

Demung is a part of javanese gamelan and considered as a xylophone-type instrument. It has thick and heavy keys mounted on a low, wooden frame. Many researchers have studied about demung and its combination with technology. This research aims to analyze the acoustic characteristic of electronic and original demung which played by human and robot, by measuring the sound frequency. The experiments are devided into 3 scenarioes. The first scenario, we measure the sound frequency of demung which hit by human. The second scenario, another frequency is measured especially from the demung that hit by robot. Whereas the last scenario, we measure the frequency of demung that comes out from electronic file. According to the experiment, it yields a conclusion that even though the frequency is slightly different for each other, but the sound produced by those 3 scenarios are almost the same.
