Over 1bn Youth Risk Hearing Loss from Headphones, Loud Music — Study
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 on Wednesday.
The World Health Organisation-led study called on young people to be more careful about their listening habits and urged governments and 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 per cent of young people had unsafe listening practices while using headphones with devices such as smartphones.
And 48 per cent were found to have been 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.
Dillard told AFP 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.
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 five percent 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.
