Here are some nice images of vibrating window frames (ooh, wow)! The finite element model I made with Python will hopefully enable me to do two things: calculate the radiation coefficient of the window frame, and calculate the effect of coupling the wooden frame with the windowpane (although shear locking is definitely a problem for the model I'm using at the moment). These things should be very central when one considers the computational airborne sound insulation of the structure as a whole.
I'm also thinking of making a more detailed model of the music box I wrote about earlier using this model at some point. That should make a fun topic for the blog.
