The Trembling Relay
Why can we hear sounds, and how do our ears work?
Right now, the air around you is trembling. A door slams, a friend laughs, a guitar twangs — and somehow, that invisible shivering becomes music and meaning inside your head. Hearing feels like magic, but it's really just a beautifully clever relay race, and your ear is the whole track.
Let's start with sound itself. Every sound is just air being pushed. When something moves — a string, a voice, a clap — it shoves the air next to it, which shoves the air next to that, like a crowd passing a nudge along. These traveling nudges are called sound waves, and they race toward your ears at about 343 meters every second.
