İnsan kulağı is the organ responsible for hearing and balance in humans. It consists of three main parts: the outer ear, middle ear, and inner ear. The outer ear collects sound waves, which travel through the ear canal to the eardrum, causing it to vibrate. These vibrations are then transmitted through tiny bones in the middle ear to the inner ear. The inner ear contains the cochlea, a spiral-shaped structure filled with fluid. When the vibrations reach the cochlea, they create waves in the fluid, stimulating hair cells that convert these waves into electrical signals. These signals are sent to the brain, allowing us to perceive sound.
