Brain wave test may reveal hidden hearing in implant users

NCT ID NCT03025386

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at whether a brain wave test called mismatch negativity (MMN) can measure how well adult cochlear implant users can tell apart similar sounds. Researchers compared the brain wave results to a standard hearing test using made-up words (logatoms). The goal was to find an objective way to check hearing, especially for people who cannot easily respond, like infants. However, the study was terminated early, so the findings are incomplete.

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 lead to an objective hearing test for cochlear implant users, especially helping infants who cannot describe what they hear.

What could go wrong

The study was terminated early, so results are limited. The approach is still experimental and may not prove reliable enough for routine use.
