What is "round window"?

The round window is a small, membrane-covered opening located in the inner ear, specifically in the cochlea. It plays a crucial role in the transmission of sound waves and the maintenance of proper fluid pressure within the cochlea. When sound vibrations enter the cochlea, they cause the fluid inside to move. The round window acts as a pressure relief valve, allowing the fluid to move and preventing damage to the delicate structures of the inner ear. This dynamic function of the round window is essential for our ability to perceive and interpret sound.
