Accoustic Computer Modelling
Accoustic Computer Modelling
(OP)
I'm interested in writing some software to simulate the sound of drums (yes I'm a drummer). However being an electrical engineer I'm a bit lost as to where to start in terms of the maths used, once I know that I should be able to find my way.
I'm looking at simulating the drum based on material properties of the shell, skin and hardware as well as the usual tension and dimensions of the drum.
So my question is, what sought of mathematical techniques, analytical or numerical do you recommend I look at?

RE: Accoustic Computer Modelling
You'd need to understand structural dynamic FEA, membrane effects, and fluid to structure interactions, and the acoustic FEM or BEM.
You might find that an empirical approach is less frustrating, it will certainly be less expensive.

RE: Accoustic Computer Modelling
What exactly do you mean by emirical, I have idea but I want to clarify?
And the acronyms are a mystery to me also
Thanks

BEM -bug-eyed monster? well, maybe you after you try to do BEM?

RE: Accoustic Computer Modelling
I think I will start by modelling just the skin and sort of build on that. I really want this to be a very comprehensive model.
