Sound as an additional learning tool

Johan Berglind
Organization: Chalmers University College

1999 International Mathematica Symposium

One of the advantages of using Mathematica in basic math courses is that it opens the possibility to create experiments in mathematics. In courses for students in electrical engineering at Chalmers University College we have used sound as an experimental tool to investigate aspects of mathematics that otherwise tend to elude students.

We give examples from two areas: ordinary differential equations and Fourier analysis. In the first example, we let Mathematica solve a differential equation with a parameter and then play the sound of the solution for different values of that parameter. The object is to find beat and resonance by listening. In the second example, we expand different functions in Fourier series and then listen to the functions and partial sums of these series.
