During his presentation, Sven used the following diagram, which he referred to as "Sven Jr.", to show the various mechanical resonances in the human body (click on the picture for a detailed diagram - 32k):
For us electrical engineers, it's important to note that the things that look like resistors in the diagram are actually springs in the mechanical engineering world, and the things that look like polarized capacitors are dampers. Sven didn't provide any information on the Q and the damping factors of the various resonances - I imagine it would vary substantially from person to person.

I've seen the human body modelled as a collection of weights in aeronautical engineering, as a collection of capacitors and resistors in static discharge studies, and now as a collection of springs in mechanical engineering. Are there other human body models out there in other branches of engineering? Let me know... Alex McEachern
