Your Ear: The Body's Most Powerful Battery (opens the original)
Read excerpt
Somewhere in your head, right now, there's a battery: a genuinely unusual electrical charge your inner ear builds and maintains for your entire life, just to make sure a whisper never gets missed. In this episode: what that battery is, why it's stranger than almost anything else in your body, and why a truly brutal week at work might actually leave a trace on what you hear.
The Dancing Cells Inside Your Ear (opens the original)
Read excerpt
There are cells inside your ear, physically changing shape thousands of times a second, stretching and contracting perfectly in time with whatever sound is around you. In this episode of Earvangelism, I break down outer hair cells: the only sensory cells in your body that work backwards, turning an electrical signal back into movement, and using that movement to amplify the very sound that triggered them.

Read excerpt
There's a tinnitus device on the market right now that uses a part of your body you'd never suspect: your tongue. In this episode of Earvangelism, I break down Lenire: why the trigeminal nerve in your tongue and your auditory pathway share brainstem wiring, and what the actual clinical evidence does and doesn't show. If you've ever wondered how the ear connects to systems that have nothing to do with hearing, this one's for you.
The Boy Who Changed How I See Learning Difficulties (opens the original)
Read excerpt
Ten years ago, a boy with dyslexia, ADHD and severe arithmetic difficulties progressed faster than every other child I was working with. After going through an intervention aimed at how he processed sound (not how he heard it). In this episode, I explain three specific, overlooked auditory factors behind learning difficulties: frequency-specific sound sensitivity, the "right ear advantage," and frequency discrimination, and why passing a standard hearing test says almost nothing about whether th
