This information applies to children only. However, it is important to mention that the adult population with hearing loss is much larger because, in addition to accumulating all children who grow with hearing loss, consider hearing losses that occur in the adult population due to ototoxicity, trauma, among others. In addition, the prevalence increases significantly with age.
Data from the World Health Organization, (WHO, 2013) indicate that 360 million people suffer from hearing impairment; this is equivalent to 5% of the world population. Of these, 165 million are people over 65 years, equivalent to 45.8%; this means that one in three people over 65 suffer some form of hearing impairment. In Latin America, the prevalence was found to be of 38.6%.
