COMMON AUDITORY DISORDERS  Presbyacusis (age related hearing loss)  Otitis media: This condition is marked by fluid in the middle ear space usually secondary to an infection.  Noise-induced hearing loss.  Otosclerosis: The condition is caused by stapedial fixation in the oval window, stiffening the middle ear system.  Ménière disease
