The World Health Organization estimates that there are over 360 million people in the world living with disabling hearing loss. As people are living longer than they did in the past, the prevalence of hearing loss has also gone up.
Close to a third of people above the age of 65 live with hearing loss.
Even though there are hearing devices that can restore a person’s ability to hear, they are commonly in short supply.
According to Dr Shelly Chadha, of the WHO’s Department of Prevention of Blindness and Deafness:
“Current production of hearing aids meets less than 10% of global need. In developing countries, fewer than one out of 40 people who need a hearing aid have one. WHO is exploring technology transfer as a way to promote access to hearing aids in developing countries.”
Of the millions of people in the world who suffer from hearing loss, only a fraction obtain hearing aids which help them overcome the difficulties. 16% of the Europeans with hearing loss have hearing aids and only 1% of Chinese do.
