Summary

This study tests whether a program called HoorToren can help 10-11 year olds use headphones and earbuds more safely. About 600 children and their parents will take part, with half receiving the lessons and home assignments. Researchers will measure listening habits through surveys and a smartphone app over a school year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
HoorToren educational package
What this could lead to
If it works, this could give schools a proven way to teach kids safe listening habits and help prevent hearing loss from loud music or headphones.
What could go wrong
This is a relatively small, early-stage trial measuring behavior through questionnaires and a phone app, not actual hearing loss. Results may not translate to long-term prevention.
