TRANSCRIPT
"Sound waves travel into the ear, making their way to a snail-shaped object called the cochlea. Once inside, they encounter hair cells that transmit the sound to the brain. But those tiny hair cells, essential to our hearing, can die if exposed to loud noise over prolonged periods of time."
