Eardrum

The ear canal sends sound waves to the eardrum.

I punctured my eardrum with a cotton bud.

Is it safe to fly with a perforated eardrum?

The eardrum is a thin, impermeable membrane.

The most common forms of hearing loss associated with anemia in the study were sensorineural hearing loss, in which the nerve pathway to the brain is damaged, and conductive hearing loss. In that condition, there is a problem with external sounds being conducted to the middle ear and eardrum.

Those exposed to the weapon experience sharp ear pain, disorientation and panic, security experts say. Prolonged exposure can cause eardrum ruptures and irreversible hearing damage.
