Which hearing test works best for preschoolers? major study aims to find out
NCT ID NCT06058767
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two common hearing screening methods—pure-tone audiometry and otoacoustic emissions—in over 13,000 preschool children. The goal is to determine which method is better at identifying hearing loss early, so children can get the help they need to avoid speech and language delays. All children will receive both tests, and researchers will compare how well each method works in a real-world preschool setting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could identify the most effective hearing screening method for preschoolers, leading to earlier detection and intervention for hearing loss.
- What could go wrong
- This is a large observational study comparing existing screening methods, not testing a new treatment. The results may show no clear advantage of one method over the other.
