Soundwaves
Each drum is unique and produces unique soundwaves. Most of us will hear the difference between a large timpani and a small drum: the former sounds much lower than the latter. But hearing the exact size and shape of a drum? Whether it’s round, oval or even square? That's a whole different story. Walter van Suijlekom investigated whether you can reconstruct the shape of an object by looking closely at soundwaves. It turns out, that it is possible! He will demonstrate this together with percussionists Niels Eijkemans and Werner van Weerenburg.
Drums and the universe
Listening to the shape of a drum may be fun, but is it useful? It is indeed. If we learn how to distinguish shapes through sound waves, we could open up a whole world of possibilities. Think of the waves picked up by large satellite dishes. Would these eventually enable astronomers to listen to the shape of the universe? Come and discover the story behind a timpani strike.
About the speaker
Walter van Suijlekom is professor of Noncommutative Geometry at the Institute for Mathematics, Astrophysics and Particle Physics at Radboud University. In his research he focuses on noncommutative geometry and its applications in particle physics. He is also a timpani player in the Nijmegen Symphony Orchestra, and this passion is reflected in his research.
Radboud Sounds
This program is part of Radboud Sounds. The festival where science meets music with lectures, dance, live music and more on Friday 12 May 2023 in Doornroosje, Nijmegen. Come and celebrate Radboud University’s 100th anniversary. Radboud University scientists from various disciplines shed their light on music and science. Come and listen, dance, enjoy and sharpen your mind on the effect of music. Compose your own program and see the world of music from a different viewpoint.
