NUMERICAL-ANALYSIS OF VIBRATION OF INDIAN DRUMS VIA COMPUTER

In this paper, the vibration characteristics of membrane of Indian dru ms have been studied using finite difference method and digital comput er. This method can be used for getting the displacement of various in stances of time. The effect of the enclosed air has also been taken in to consideration. The displacement and damping characteristics for uni form single, double and triple membranes which are centrally loaded ha ve been plotted. It was found that the damping is much slower and bett er harmonics are developed when these membranes are used for drums as in case of Indian drums than drums with single membrane.
