ELI5: How do our ears not flood when we go underwater?
gpt
Hi, studying audiologist here! Basically there are separate sections to our ears: the outer ear (what you can see) the middle ear which is between the ear drum and the cochlea, and the inner ear (cochlea). The ear drum is a complete wall sealing the outer and middle ear apart from each other, so unless there’s a medical issue which you would KNOW from the pain, there’s no way that water, dirt, dust etc could get through your ear drum and into your ear :)
