How does the external auditory canal transmit sound waves to the inner ear?
The external auditory canal collects sound waves and funnels them towards the eardrum. The eardrum vibrates in response to the sound waves, which then transmit the vibrations to the three small bones in the middle ear. These bones amplify the vibrations and send them to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for interpretation.

ear wax, or also called cerumen. Ear wax moves out dust and other small particles. It collects dirt and other debris in your ear canal and moves it out of your ears as you clean your external ears. Cerumen also helps prevent foreign substances (including insects) from entering the auditory canal. It also forms a protective layer of wax in the ear canal which is a water repelling shield. Ear canals need to be dry to be healthy. The wax is also slightly acidic and will prevent the growth of fungi and bacteria. It also fights infections.
