Common causes of conductive hearing loss include: 1  Cerumen (earwax) or foreign body in the external auditory canal. 2  Otitis externa, infection or irritation of the outer ear.  Exostoses, abnormal growth of bone within the ear canal.
Conductive hearing loss is associated with impaired transmission of sound waves through the external ear canal to the bones of the middle ear. A blockage of the external ear or dysfunction of the middle ear will produce conductive loss of hearing.
