UNITED NATIONS: The World Health Organisation (WHO), a Geneva-based UN agency, says over one billion people, aged 12 to 35, risk losing their hearing due to prolonged and excessive exposure to loud music and another high volume recreational noise. The agency gave the warning in new international safety advice on Wednesday to tackle the rising threat of hearing loss. The launching of a new international standard for safe listening at venues and events coincided with World Hearing Day marked today (Thursday) on the theme, ‘To hear for life, listen with care!’ It applies to all places and activities where amplified music is played. Over 1.5 billion people globally live with hearing loss, and according to recent estimate, this number could rise to over 2.5 billion by 2030. WHO estimates that 50 per cent of hearing loss can be prevented through public health measures. According to WHO, many common causes of hearing loss can be prevented, including over-exposure to high volume sounds. “Millions of teenagers and young people are at risk of hearing loss due to the unsafe use of personal audio devices and exposure to damaging sound levels at venues such as nightclubs, bars, concerts and sporting events,” said Dr Bente Mikkelsen, WHO Director for the Department for Noncommunicable Diseases. “The risk is intensified as most audio devices, venues and events do not provide safe listening options and contribute to the risk of hearing loss”, she added. The new WHO standard aims to better safeguard young people as they enjoy their leisure activities. The “Global standard for safe listening at venues and events,” highlights six recommendations for implementation to ensure that venues and events limit the risk of hearing loss to their patrons, while still preserving high-quality sound and an enjoyable listening experience. The six recommendations outlined as 1) A maximum average sound level of 100 decibels; 2) Live monitoring and recording of sound levels using calibrated equipment; 3) Optimizing venue acoustics and sound systems to ensure enjoyable sound quality and safe listening; 4) Making personal hearing protection available to audiences including instructions on use; 5) Access to quiet zones for people to rest their ears and decrease the risk of hearing damage, and, 6) provision of training and information to staff. WHO alerted that hearing loss due to loud sounds is permanent, underlining that exposure to loud sounds causes temporary hearing loss or tinnitus (ringing sound interference in the ears), and prolonged or repeated exposure can lead to permanent hearing damage, resulting in irreversible hearing loss. 7) Young people can better protect their hearing by: i. Keeping the volume down on personal audio devices, ii. using well-fitted, and if possible, noise-cancelling earphones/headphones, iii. wearing earplugs at noisy venues, getting regular hearing check-ups. Calling for the new global standard to be supported, WHO encouraged governments to develop and enforce legislation for safe listening and raise awareness of the risks of hearing loss. The UN agency also advised that behaviour change can be motivated by civil society organizations, parents, teachers, and physicians, who can educate young people to practice safe listening habits. “Governments, civil society and private sector entities such as manufacturers of personal audio devices, sound systems, and video gaming equipment as well as owners and managers of entertainment venues and events have an important role to play in advocating for the new global standard,” said Dr Ren Minghui, WHO Assistant Director-General. “We must work together to promote safe listening practices, especially among young people”, he added.
