UN WORLD HEALTH STATS - 2017: Hearing loss is the worlds No. 1 disability. One-third of people over the age of 65 and two thirds over the age of 80 will be exposed to hearing loss. Also, undetected hearing loss in infant children sometimes results in speech defects, that are sometimes not correctable even if the hearing is restored. In addition, persons in their lifetime can lose hearing through injuries, infections and disease. The total number of persons suffering hearing loss worldwide is nearly 1 billion. The economic loss to all nations is unmeasurable, let alone the emotional trauma of deafness and hearing loss to all.
