| Hearing Did you know your outer ear is called the auricle? But it’s your inner ear that hears the ‘phone call It’s got a lot of moving parts It’s quite the magical factory. The human ear Is quite the magical factory. Now when those sound waves travel your ear canal You know the first thing they touch is your eardrum And then it starts to vibrate sound It’s stretch so tight it’s got to vibrate sound. Just like a big bass drum Stretch so tight it’s got to vibrate sound. On the other side of your eardrum The three smallest bones in your body The hammer, the anvil, the stirrup Take the vibrations from your eardrum And make them stronger. At the end of this chain of your smallest bones A thin tissue leads to your inner ear Connected to the cochlea It’s a bony thing like a small snail shell. And when the three small bones make that liquid move Nerve cells in your cochlea Send a message to your brain And now you understand about hearing. Well I’d tell you again But like I told you before I heard your ‘phone ring. |
