Hi alephzero,
thanks for your great insight and knowledge sharing,
As the soundfile can be user defined I cannot measure any values in advance sadly, so I have to come up with a computational solution.
In my model I did'nt include any fluid-membrane interaction besides the passive...
Yea, your right, for all modes mn I'd like to know their amplitude if it is excited by a certein sound.
Let's just think for a moment that this is done by pure resonance and not by any direct physical impact of the air, so i don't excite the membrane directly. Just like in the video:
How...
Thanks for the answer Gordianus.
And what am I going to do with the peaks afterwards? How can I map them to the vibrations?
I mean If i get a frequency of 10, how should I map it to the other base? In the case of a circular membrane I get floating point values for each mode, for example...
Thank you for the answer. To be a bit more specific: I use it together with a fluid simulation in order to model an experiment, where they placed some paint on top of the membrane, which was wrapped over a speaker. When they let sound through the speaker, the membrane starts to vibrate...
Does nobody have an idea? Would be really great, as I am working on a Project, that could reaaally use this. Just ask in case the question is not clear.Selim
Hey everybody,
I'm trying to figure out what the vibration modes of a circular membrane would look like if we put some sound through it.
As you may know does a circular membrane with clamped edges at radius a behave according to the wave equation.
The general solution thereof has the form...
