In order to really get to the nitty-gritty of how your ears pick up sound, you've got to understand how sound works.

为了真正了解你的耳朵是如何接收声音的，你必须理解声音是如何工作的。

The outer ear picks up sound waves from the air around it and moves them along your ear canal to the middle ear, where the sound waves vibrate the eardrum, sending the sound along to the inner ear.

外耳从周围的空气中收集声波，然后将其沿耳道传递到中耳，声波会在此振动耳膜，从而将声音传递到内耳。
