Fact Fly: How Do We Make Sound?

The Fact Fly’s One Big Question

How do we make sound when we talk — and why does your voice sound so different when you hear it on a recording? Join Lauren and the Fact Fly as they investigate the surprisingly amazing science behind the most incredible instrument ever made: you. From the tiny vibrating vocal folds inside your larynx to the air from your lungs that turns those “little strings” into sound, this episode reveals how your body transforms a simple buzz into words, songs, whispers, shouts, and your one-of-a-kind voice.

You’ll discover why high notes and low notes work like tightening and loosening guitar strings, how your tongue, lips, teeth, mouth, skull, and sinuses all help shape sound, and why singing is basically “the voice box turned up to 11.” Then the Fact Fly takes a wild tour through the animal kingdom to find out how birds harmonize with themselves, whales sing across oceans, elephants communicate through the ground, crickets play their wings like tiny fiddles, and bats use sound to “see” the world. Plus: the mystery of why your recorded voice sounds weird — the answer involves bone vibrations, air vibrations, and the fact that everyone else has been hearing your voice differently all along.

Perfect for singers, talkers, animal-sound lovers, curious kids, and anyone who has ever heard their own voice on a recording and said, “Wait… is THAT what I sound like?”
