Human frequency and muscle contractions

[Mel2103]

Is possible for human muscles to contract from resonance at certain levels/ranges of frequency?

I have been a lot about how with the right frequency, one can induce contractions in diff parts of the human body. Does anyone know about this? If this is true, then what is the way you can dampen the frequency, assuming the the frequency is transmitted via vibrational energy? The dampeners currently in the market seems to be targeted only toward frequencies of music and more structural/mechanic sorts.

(I apologize if I am not using very techy physics term; I only took 1 year of college physics)

That's pretty much how a Taser works, so yes... it is definitely possible.

I think he's talking about sonic frequencies, and I have not seen anything like that.

Oh... I misunderstood that. Sorry.

Well, I have been reading other posts on this forum about this phenomenon, about how human body frequency being in the range of 5 to 10 hz, with the suggestion that muscle contraction of diff parts of body are possible by varying the frequency. Apparently this phenonemon has been exploited for use by the US gov't as a potential military weapon against the enemies.

I don't mean sonic frequency in the sense that there is no medium to transfer this energy other than air. I am interested in vibrational energy, whether it be caused by sound or some other sheer mechanical source and how that causes muscle contractions in the human body. So, you see, it is not that far-fetched.

More importantly, how can this be dampened? Standard vibrational dampers do not address this issue since it focuses mainly on frequency related to music or structural noises.

You could set off an explosion between you and the source, but I suspect that it might be counter-productive.
