Could a simple device shape a Child's brain? hearing aids put to the test
NCT ID NCT07774728
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether giving behind-the-ear hearing aids to young children (ages 6 months to 4 years) with mild hearing loss can improve their overall development, especially language and brain growth. Half the children will receive hearing aids, while the other half will not, and both groups will be followed for a year. Researchers will measure developmental progress and use brain scans to see if hearing aids make a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Behind-the-ear (BTE) hearing aids
- What this could lead to
- If effective, this could support early hearing aid use as a standard care to improve language and brain development in children with mild hearing loss.
- What could go wrong
- The trial is relatively small and early, and results may not apply to all children. Hearing aids may not fully restore normal hearing, and some children may not benefit as expected.

Inclusion Criteria: * Age: ≥0.5 years and \<4 years * Diagnosed with bilateral mild sensorineural hearing loss by objective hearing tests: bilateral click-ABR ≥35 dB nHL and ≤50 dB nHL, with bilateral type A tympanogram (including As/Ad type) on acoustic immittance testing * Without previous hearing aid intervention Exclusion Criteria: * Premature and low birth weight infants: gestational age less than 37 weeks, or birth weight below 2500 grams * Participants diagnosed with enlarged vestibular aqueduct (EVA) by imaging (CT, MRI) or genetic testing * Participants with complicated medical problems or significant disabilities affecting growth and development (such as autism, recurrent epilepsy, severe heart disease requiring multiple surgeries, etc.) and considered unsuitable for this study by the investigators * Families who refused to participate in this study, or have already decided whether the participant will wear hearing aids or not (refused to randomization). * Participants who refused/was unable to undergo study assessments as scheduled.
