Sounds from Vibrations

Just yesterday, i was going through this article which said that every object, that vibrates has got its own frequency. Now again, sound is produced when an objects vibrates i.e. has its own frequency. Typically, humans can hear on a frequency range from 20Hz to 18~19kHz. (Not 20kHz, thats only theoretical).

So, any goddamn thing vibrating at this range of frequency can produce sound audible to human ear.

This however does not means that vibrations at any other frequency would not be producing any sound at all. ( Dogs can hear at pretty high frequency than humans can hear.)

Now, i would draw your attention to objects at atomic level.

We know that at the atomic level, every atoms vibrate with their own unique frequency! So then, if we correlate the ideas, then we come to a point where we can imply that every object, even if it is static in normal state produces a sound by itself. If such is the case, then the if by any means we can pick up the frequency of an object, then we can detect objects with out so much of trouble.

Honestly, I have not thought upon the implications of this idea, but potential and the scope for this remains open and to the infinite.
