Event details

ISVR Research seminar

Idakkā is a drum which is noted for its musical quality. Its ability to produce sounds of a definite pitch with numerous harmonic overtones makes it fairly unique among drums. In this talk, the musical nature of this drum is explored through the analysis of audio recordings. Then, a mathematical model of the drum is proposed. It is shown from numerical simulations that the harmonic nature of the idakkā can be partially explained by the interaction of the drumhead and two thin string which are behind the drumhead. The harmonic nature thus established is validated using nonlinear normal modes. As part of this work, we also propose a minor improvement in numerical modeling of string membrane collision interactions, valid in a restricted parameter range.
