How many people have hearing loss?
Over 1.5 billion people — about 20% of the world's population — live with some degree of hearing loss. Of these, 430 million require rehabilitation services. By 2050, the WHO projects this will rise to 2.5 billion. Hearing loss is the third most common physical condition after arthritis and heart disease.
