Abstract

The African djembe drum consists of a goat skin stretched over a hand‐carved shell with a large cavity, open at the bottom. The shape of the shell cavity acts as a Helmholtz resonator, providing a strong bass component around 75 Hz. The shell exibits several bell‐ or wineglass modes, some of which have frequencies close to membrane modes. This talk will present results from acoustic and modal analysis tests of the drum with and without the skin membrane intact. Mode shapes and frequency spectra will be presented as well as a discussion of how the shell, cavity, and membrane couple together to provide the djembe’s unique sound.

Study Snapshot

Key takeawayThe African djembe drum's unique sound is influenced by the shape of the shell cavity, the goat skin, and the membrane, which all contribute to its unique sound.
