Sound travels invisibly through the air toward you. You do not see it coming, but your ears are already listening, already gathering what the world is trying to tell you. Tonight on The Bedtime Scientist, we follow the path sound takes through the human ear, from sound waves in the air, to the eardrum, through the tiny bones of the middle ear, and into the cochlea, where thousands of delicate hair cells turn vibration into signals your brain can understand.

This is a gentle bedtime exploration of how hearing works, how ears receive sound, and how listening connects you to the world around you. Perfect for curious kids who love science, the human body, and the five senses.

The Bedtime Scientist features one steady voice, real science, no music, and no sound effects. Just the gentle work of noticing.
