More than 360 million people have disabling hearing loss, according to new global estimates released by the United Nations World Health Organization (WHO), which adds that production of hearing aids is not keeping up with the urgent demand. Another 32 million people affected by hearing loss are children under the age of 15. Many of whom live in low- and middle-income countries – particularly in South Asia, Asia and the Pacific and sub-Saharan Africa – where untreated ear infections lead to hearing loss.
