Around 90 million children and adolescents aged 5 to 19 live with hearing loss worldwide. Many cases go undetected, especially in low-resource settings. One billion young people, particularly adolescents, face risk from prolonged exposure to loud sounds. The World Health Organization estimates that unaddressed hearing loss costs the global economy more than 980 billion dollars each year and puts progress on poverty reduction at risk. Adults with hearing loss face higher odds of low income and unemployment or underemployment compared to peers with typical hearing.
World Hearing Day on 3 March 2026 places children at the centre, under the theme: From communities to classrooms, hearing care for all children. CBM will highlight evidence from our programmes, demonstrating how we prevent childhood hearing loss and advance regional advocacy efforts to strengthen ear and hearing health.
