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 caused by a mechanical problem along the route from noise in the environment to the inner ear. It could be a problem with one of the three small bones collectively called the ossicles (the stapes, malleus, and incus), or other parts of the ear that fail to conduct sound to the cochlea.
