n. an eardrum with a hole or tear in it; can interfere with normal hearing and cause other ear problems
Wikipedia
A perforated eardrum or punctured eardrum is a rupture or perforation (hole) of the eardrum which can occur as a result of otitis media (ear infection), trauma (e.g. by trying to clean the ear with sharp instruments), explosion, loud noise or surgery (accidental creation of a rupture). Flying with a severe cold can also cause perforation due to changes in air pressure and blocked eustachian tubes resulting from the cold. This is especially true on landing.
Perforation of the eardrum leads to conductive hearing loss, which is usually temporary. Other symptoms may include tinnitus, earache or a discharge of mucus.
