Up to 1.35 billion people could lose their hearing due to too loud music on headphones.

The researchers analyzed more than 30 scientific papers on this topic over the past 20 years. In the studies analyzed by scientists, a total of about 20 thousand people participated. It turned out that in 24% of cases, listening to music with headphones can be called dangerous. In the case of concerts, this figure reaches 50%. The researchers also found that listening to loud music was associated with "changes in hearing thresholds." This is due to the fact that sensory cells are damaged in humans, and it takes years to restore them.
