Does the human body have resonance frequency?

I don’t have any factual evidence; but as an Audiologist, I am inclined to say no. The components of our body vary too greatly in density, size, shape and rigidity to share one common resonant frequency.

Every physical object in nature has a resonant frequency, but soft, squishy things like a human body have a very low Q factor, which means there is too much damping for you to notice. Things with high Q factors tend to resonate sharply within a narrow frequency band. A block of wood in a xylophone, for example, resonates at a specific frequency when struck, but does not do it for very long. A metal bar in a marimba or vibraphone also resonates at a specific frequency, and rings for a much longer time because it has a higher Q factor.

I think my ears must have a very high Q factor

I know that the one reason that people are kept so far away from rocket launches is due to low frequency vibrations that can damage internal organs.

As for the whole body, wouldn’t we need to be more rigid to have a natural frequency.

@lercio , a human body does have a natural resonant frequency, but because of what I mentioned above, it’s insignificant. A graph of the body’s Q factor,

would be nearly flat. For something like an organ pipe, it’s very narrow.

Yes, I believe the human body resonates at the musical note B Natural, but 217 octaves lower than the lowest B Natural on the piano…one octave being 8 notes, thus: 217 X 8 = 1736…
Think about the extreme difference of the highest and lowest notes…then take that extremity and times it by about twenty. So, if a device was made that could produces this resonance, any humans nearby would…explode. Dissipate. Sort of like what happens to a glass when its resonance is matched. It just sort of…shatters. Same would happen to anything if its resonance is matched by sound.
