International Ear Care Day highlights hearing loss problemListen /
The World Health Organization (WHO) says the highest prevalence of the problem is found in Asia Pacific, South Asia and sub-Saharan African.
The agency points out that about half of all cases of hearing loss worldwide are preventable.
To raise awareness about hearing issues, International Ear Care Day is observed on 3 March each year.
WHO says the date was chosen because of the shape of the numbers 3.3 to represent the two ears.
To find out more about hearing loss, UN Radio's Patrick Maigua spoke with Dr Shelly Chadha of the WHO Unit for the Prevention of Blindness and Deafness.
