Live Desk: Around one billion young people worldwide could be at risk of hearing loss from listening to headphones or attending loud music venues, a large review of the available research estimated, reports AFP.
The World Health Organization-led study called on young people to be more careful about their listening habits and urged manufacturers to do more to protect future hearing.
The analysis published in the journal BMJ Global Health looked at data from 33 studies published in English, Spanish, French, and Russian over the last two decades covering more than 19,000 participants aged between 12-34.
It found that 24% of young people had unsafe listening practices while using headphones with devices such as smartphones.
It also found 48% were exposed to unsafe noise levels at entertainment venues such as concerts or nightclubs.
Combining these findings, the study estimated that between 670,000 to 1.35 billion young people could be at risk of hearing loss.
The wide range is partly because some young people are probably at risk from both factors, said Lauren Dillard, an audiologist at the Medical University of South Carolina and the study's first author.
Ms Dillard said the best way for people to lessen their risk of hearing loss from headphones is to turn down the volume and listen for shorter periods.
"Unfortunately, people do really like very loud music," she admitted.
Headphone users should use settings or apps on smartphones to monitor sound levels, she advised.
In loud environments, noise-canceling headphones can help avoid "cranking up your music to try to drown out all that background noise", Ms. Dillard added.
Earplugs should be worn at loud events like concerts or nightclubs, she said, adding, "Maybe it's fun to be in the front by the speakers, but it's not a good idea for your long-term health.
"All of these behaviors, these exposures can compound over the course of your entire life, and then when you're 67 years old, it can have a pretty big impact."
Ms. Dillard called on governments to comply with WHO guidelines on safe listening, including making sure venues monitor and limit music levels.
She also urged companies that make devices like phones to warn listeners when the volume is too loud and to include parental locks to restrict children's exposure.
Limitations of the research included the varying methodologies across different studies and that none came from low-income countries.
Stephen Stansfeld, an expert on noise and health at the Queen Mary University of London who was not involved in the research, said it showed "the potential for serious population-wide hearing loss is very large".
More than 430 million people, over 5% of the world's population, currently have disabling hearing loss, according to the WHO, which estimates the number will rise to 700 million by 2050.
