Modal Analysis of a “Tongue Drum”

Jonathan South Modelling & Simulations December 11, 2019

[EDIT]: Updated to a later version of MATLAB (2019a), so code has been updated to suit. Also, see the follow up for time domain simulations! We’ve had a look at using finite element analysis to solve the wave equation in 2D geometries to find room modes and resonances (here), so the next step up is

Acoustic Eigenmodes and the Helmholtz Equation

Jonathan South Fundamentals August 20, 2018

You are hopefully well aware of room modes and resonances. As the bane of home recording spaces, they have the ability to wreak havoc on small, untreated rooms. Physically, they are the result of standing waves, sound reflecting between surfaces in such a way that they reinforce themselves. They are based on the geometry of
