4. Hearing and Language: Hacks 44–52 > 47. Keep Your Balance

Keep Your Balance

The ear isn’t just for hearing; it helps you keep your balance.

Audition isn’t the only function of the inner ear. We have semicircular channels of fluid, two in the horizontal plane, two in the vertical plane, that measure acceleration of the head. This, our vestibular system, is used to maintain our balance.

Note that this system can detect only acceleration and deceleration, not motion. This explains why we can be fooled into thinking we’re moving if a large part of our visual field moves in the same direction—for example, when we’re sitting on a train and the train next to ours moves off, we get the impression that we’ve started moving. For slow-starting movement, the acceleration information is too weak to convince us we’ve moved.
