Conductive hearing loss
A conductive hearing loss is due to a problem in the outer or middle ear which makes it difficult for the sound to reach the inner ear. It can be both temporary and long-term.
The most common causes of a conductive hearing loss can be a build-up of wax in the ear canal, a perforated eardrum, fluid in the middle ear (which is common in children) or damage to the middle ear bones (the ossicles).
