The World Health Organization organizes World Hearing Day every March 3. The observance began in 2007 as "International Ear Care Day," following the Beijing Declaration issued at the first international conference on the prevention and rehabilitation of hearing impairment, before WHO adopted its current name, World Hearing Day, in 2016. The date 3/3 was chosen because the digits resemble a pair of ears. The day raises awareness that hearing loss affects hundreds of millions of people worldwide, and that a large share of cases can be prevented or treated if detected early — through vaccination, protecting ears from loud noise, or regular screening, especially for newborns and older adults. Health ministries and medical associations around the world mark the occasion with free hearing screening campaigns, workshops on the safe use of headphones and phones, and educational talks aimed at families and schools.
