Speaker: Joachim Worthington (University of Sydney postgraduate) Why are sine waves like prime numbers for sound? How can Chebyshev Polynomials make instruments "sweeter"? If you’re going to play a song by smacking a rock with hammers, which hammers should you use? And why do Bessel Functions sound like a bell? This talk will hopefully answer these questions, while introducing some of the basic principles of synthesis and sound design. Some surprising links between simple sounds and complex mathematics will be demonstrated, and some surprising and perhaps defeaning noises will be made. One mathematics talk you definitely won’t be able to sleep through!
