![]() ![]() It converts soundwaves into nerve impulses that travel to the brain via the movement of tiny hair cells. The inner ear consists of the cochlea and the nerve of hearing. The middle ear functions to amplify sound, which is why significant hearing loss can result from any disruption in any of its parts. The hammer moves the anvil, which moves the stirrup, transmitting the vibrations into the inner ear. These sound waves are amplified up to 20 times of original waves. When the hammer vibrates, it transmits the sound to the other two bones, i.e. As the hammer is connected to the eardrum. They are commonly referred to in English as the hammer, anvil, and stirrup. When soundwaves hit the eardrum, it vibrates and moves the hammer. Three ossicles called the malleus, incus, and stapes.
