To fully understand the complexity of hearing loss it is worth noting the different types of hearing loss that are typically encountered today. For example, conductive hearing loss is a common type of hearing loss that affects the outer or middle ear. This condition can be caused by a number of problems. From excessive wax in the ear canal to an infection or some type of inner ear related bone disease, there are many reasons that conductive hearing loss may occur. Having a comprehensive hearing and audiology exam is often the best way to know for sure. Sensorineural hearing loss is another condition that can have a direct effect on hearing.
