World Hearing Day is a campaign held each year by Office of Prevention of Blindness and Deafness of the World Health Organization (WHO). Activities take place across the globe and an event is hosted at the World Health Organization on March 3. The campaign’s objectives are to share information and promote actions towards the prevention of hearing loss and improved hearing care. The first event was held in 2007. Before 2016 it was known as International Ear Care Day. Each year, the WHO selects a theme, develops educational materials, and makes these freely available in several languages. It also coordinates and reports on events around the globe.
