Nearly 50% of people aged 12-35 years – or 1.1 billion young people – are at risk of hearing loss due to prolonged and excessive exposure to loud sounds, including music they listen to through personal audio devices. Ahead of World Hearing Day (3 March), the World Health Organization (WHO) and the International Telecommunication Union (ITU) have issued a new international standard for the manufacture and use of these devices, which include smartphones and audio players, to make them safer for listening.
"Given that we have the technological know-how to prevent hearing loss, it should not be the case that so many young people continue to damage their hearing while listening to music,” says Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "They must understand that once they lose their hearing, it won’t come back. This new WHO-ITU standard will do much to better safeguard these young consumers as they go about doing something they enjoy.”
Over 5% of the world’s population – or 466 million people – has disabling hearing loss (432 million adults and 34 million children); impacting on their quality of life. The majority live in low- and middle-income countries. It is estimated that by 2050 over 900 million people – or 1 in every 10 people – will have disabling hearing loss. Hearing loss which is not addressed poses an annual global cost of US$ 750 billion. Overall, it is suggested that half of all cases of hearing loss can be prevented through public health measures.
