Human Body Resonant Frequencies

Since the old topic is locked, I had to post a new one about this
(old topic here: http://www.physicsforums.com/archive.../t-231156.html )

People were talking about resonant frequencies for body parts and/or the entire body and someone was looking for a chart, not sure if this is the one from NASA which they had mentioned but it appears to follow the numbers I am seeing in various research I can find out there (such as research conducted about pilots, as well as the Harvard study posted in the previous thread)

Brilliant, thank you for this!

Where did you get this picture and what study is it based on?

What is the significance of resonant frequency in the body?

I forget where I found the image, but studies are abundant. Here are a couple:

(I can't make clickable links due to not having 10 posts here, pfft great rule for a physics forum, not like anyone would need to cite references here!)

As for significance, I would assume that would be self-evident... Anything from sonic weaponry, brown notes, safety in the operation of machinery, or maybe even music that can make your knees feel weird or cause hallucination. The applications could be quite interesting.

I'd like to thank the mods for unlocking this thread. I appreciate it. I wanted to cite a couple more references for anyone else out there wondering about the figures posted in the chart:
