What Wikipedia says

A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation.
