The outer earSounds from the outside world are picked up by the outer ear, which is made up of the pinna and the ear canal. As the sound waves enter the ear, the ear canal serves to increase the loudness of those pitches that make it easier to understand speech. At the same time the ear canal (1) protects another important part of the ear: the eardrum (2) - a flexible, circular membrane that vibrates when touched by sound waves.The middle earThe sound vibrations continue their journey into the middle ear, which contains three tiny bones called the ossicles (3, 4, 5) (more commonly known as the hammer, anvil and stirrup). These form the bridge from the eardrum into the inner ear. They increase and amplify the sound vibrations even more, before safely transmitting them on to the inner ear via the oval window.The inner earThe inner ear, or cochlea,The outer earSounds from the outside world are picked up by the outer ear, which is made up of the pinna and the ear canal.
