The waves then make their way across a membrane that separates the middle ear from the inner ear, which houses the fluid-filled, snail-shaped cochlea. Indeed, as the National Science Foundation acknowledges, “human hearing is a process full of unanswered questions,” especially from a cognitive perspective.īut we do know that, when a noise is made, sound waves enter the ear canal and register on the eardrum and in the tiny bones of the ear (malleus, incus, and stapes). It’s difficult to provide a succinct description of hearing without misrepresenting how it works. While congenital deafness is usually caused by anomalies in the inner ear, there is a cognitive component to hearing that not only describes how sounds get processed by the brain, but which may account for some hearing problems as well. ![]() Research suggests that hearing loss isn’t all in the ears where we typically think of hearing taking place.
