Does the human body have a resonant fequency? If so, how strong is it?

Question

Inpired by http://music.stackexchange.com/questions/7064/physiological-responses-to-different-rhythms, I'm wondering if the human body has a strong resonant frequency. I guess the fact that that it's largely a bag of jelly would add a lot a damping to the system, but is that enough to dampen it entirely?

What models for resonance might be used to model the human body? (eg. weight-on-a-spring, with legs as springs?). What about individual, semi-independent body parts, like legs, or lung cavity (acoustic resonance?).

Answer 1

There seem to be a lot of human body mechanical models, such as this one:

As for applications, I have heard that sub-audio frequency vibrations have been considered as nonlethal weapons for riot control.
