The Inner Ear (Cochlea)
... For an object to produce a sound, it has to vibrate matter. This matter could be solid like the earth or liquid like water, but most of the time it is gaseous in the form of air. When the item vibrates, it starts a chain reaction and moves the particles directly surrounding it, which in turn cause t ...

Ear Infection and Hearing Loss
... Otitis media refers to inflammation of the middle ear. When an abrupt infection occurs, the condition is called "acute otitis media." Acute otitis media occurs when a cold, allergy, and the presence of bacteria or viruses lead to the accumulation of pus and mucus behind the eardrum, blocking the Eus ...
