The eardrum

Explanation:

The eardrum is the part of the ear structure. This part is very important. It plays a great role in hearing impairment. It is very important for listening. It is also called the tympanic membrane. This membrane separates the ear part ear canal from the middle ear.

Tympanic membrane proliferation occurs for many causes. It depends on the size and whole f the eardrum. If proliferation occurs it creates a conducive hearing impairment in a person or a child. Due to this the middle ear does not get wet or liquid form. But if water enters the middle ear it creates a middle ear infection.  

Thus eardrum plays a vital role in hearing and impairment in the ear.
