VIBRO-ACOUSTICS OF THE SOUTH INDIAN DRUM: MRIDANGAM

摘要

This paper presents a summary of the ongoing research to develop a vibro-acoustic model of Mridangam - A South Indian drum. Various components of this instrument such as the wooden body structure, acoustic cavity inside the body as well as the membranes of the drum are analyzed to understand their role in producing the music. The analysis involves both experiments and finite element simulations. The coupled behaviour of the membrane and air cavity is demonstrated using an idealised mridangam membrane model from the literature.
