What are the types of hearing loss?
a hearing loss that occurs when sound waves cannot transmit through the outer or middle ear or both. This can, for example, be caused by earwax, middle ear infections, or a punctured eardrum. The most common cause of conductive hearing loss, which mainly affects children, is otitis media. This is often associated with temporary or fluctuating hearing loss. This in turn can affect a child’s learning, language development, and behavior.
a hearing loss that usually develops due to damage to the small sensory cells in the inner ear, or the hearing nerves. Sensorineural hearing loss may be congenital or acquired. This damage can occur as a result of disease, illness, age, injury from exposure to noise or certain medicines, or as the result of a genetic disorder.
a combination of conductive and sensorineural hearing loss. For example, an individual may have a sensorineural hearing loss that is due to presbycusis and conductive hearing loss as a result of a perforated eardrum.
