Simple Room Resonance Analysis

Jonathan South Modelling & Simulations, Room Acoustics September 1, 2018

Lets put some theory to the test by finding the room resonances of simple (and maybe not so simple) 2D polygonal rooms using computational methods. I’ll explain the code, and provide a file for download as well. The Problem To find room resonances, we need to solve the Helmholtz Eigenvalue problem (see here for why)

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
