Back then you couldn't even look at the eardrum.

The smallest sound you can perceive moves your eardrum just four atomic diameters.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

The important thing to remember is that even if an earwig found its way into your ear, it would never eat through your eardrum.

Somehow in tickling our eardrum that transmits energy down our hearing bones, which get converted to a fluid impulse inside the cochlea and then somehow converted into an electrical signal in our auditory nerves that somehow wind up in our brains as a perception of a song or a beautiful piece of music.

An 11 inch, and it's actually the vib, it's the vibrations of the string affecting the, the air, and then, the, the air compressions eventually get to our eardrum. And that's what actually gives us the, the perception the sound, but we don't want to delve too much into the physics of it. An 11 inch string has a frequency.
