So if the round window or if the oval window becomes rigid, meaning it's not going to vibrate as much, that means our wave inside would not be as strong, and that implies we would not be able to hear as well. So the reason we're able to hear well is because these windows, these membranes, are flexible and they're able to oscillate and move back and forth. So as the pressure wave is carried through our cochlea, inside the cochlea, we have a region known as the organ of corte. And at the organ of corte, we basically have specialized types of sensory cells known as hair cells. And these hair cells contain these extensions known as Microville. And these Microville extensions basically are capable of accepting these pressure waves.
