Earbuds and festivals, two distinct products of the 21s Century, and a millenial staple, may be toblame for a shocking new study on hearing loss.

Conducted by Ontario’s McMaster University found that 30% of teenagers surveyed already suffered from Tinnitus, a condition that creates a consistent ringing or buzzing in the ears. Study coauthor, Larry Roberts expresses his long tern concern on the findings with, “there is a major public health challenge coming down the road in terms of difficulties with hearing”.

The World Health Organization (WHO) has already expressed its own concern that some 1.1 billion young people are at risk for Tinnitus around the world, specifically due to the prevalence of in ear music players and extreme decibel levels at entertainment venues (festivals, for example, frequently perform at over 120 db – according to the WHO anything over 85 db can cause hearing loss).

According to experts, the best way to protect ears the “60/60” rule: Keep the volume under 60 percent and listen for a maximum of 60 minutes a day.
