Classroom lessons aim to stop hearing loss before it starts
NCT ID NCT07513077
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
