Your hearing is done by a 'field' of very fine hairs inside your ear canal
that flex with the air movement that we call sound.

An otherwise excellent post, but just to avoid unintentionally
misleading anyone, those hairs flex indirectly with the air movement
(localized variations in pressure) which we call sound. Those hairs
are in a fluid-filled chamber to which the vibrations of your eardrum
caused by sound are coupled through some little bitty bones. The air
doesn't move those hairs directly, and as far as I know they have
absolutely nothing to do with those "other ear hairs" that show up and
start growing like crabgrass somewhere in middle age.
