I. axons of the neurons associated with each hair cell that carry information to the brain
II. hair cells (the sensory receptors) in the cochlea
III. tympanic membrane, or eardrum

All of the above

Explanation:

axons of the neurons associated with each hair cell that carry information to the brain & hair cells (the sensory receptors) in the cochlea & tympanic membrane (eardrum).

Sudden hearing loss in 1 ear may be due to earwax, an ear infection, a perforated (burst) eardrum or Ménière's disease.

Sudden hearing loss in both ears may be due to damage from a very loud noise, or taking certain medicines that can affect hearing.

The inner ear is home to some of the most delicate bones in the body, and damage to the eardrum or middle ear can cause hearing loss and deafness in a range of ways.
