The middle ear bones then transfer the vibrating signals to the inner ear.

The eardrum, also known as the tympanic membrane, is a thin layer of tissue that separates the outer ear from the middle ear.A hole in the eardrum can be caused by: 1  a middle ear infection, if pus builds up inside your ear and puts pressure on your eardrum.2  an injury to the eardrum, such as a severe blow to the ear or poking an object such as a cotton bud deep into the ear. 3  a sudden loud noise, such as a loud explosion.our GP may prescribe antibiotics if your perforated eardrum was caused by an infection or if there is a risk that an infection will develop while your eardrum heals. You can reduce your risk of developing an infection by keeping your ear dry until it's healed.
