Could a new test help hearing aid users hear better in crowds?
NCT ID NCT07756970
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This study tests whether using a special hearing-in-noise diagnostic (the ACT test) to fit hearing aids improves speech perception, spatial awareness, and user satisfaction compared to standard fitting. Adults aged 18-50 with moderate to severe hearing loss who use bilateral hearing aids will be monitored with speech-in-noise tests and questionnaires. The goal is to see if this personalized approach helps people hear better in real-world noisy situations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- ACT diagnostic test for hearing in noise
- What this could lead to
- If effective, this diagnostic could help audiologists tailor hearing aid settings to improve speech understanding in noisy environments, potentially boosting user satisfaction.
- What could go wrong
- The trial is small and early, and results may not apply to all hearing aid users. The test's benefit over standard fitting remains uncertain.
