Study summary

Hearing loss, especially for speech perception in the presence of noise, may lead older individuals to withdraw from social situations. While hearing aids help amplify sound and are useful in many situations, they can be ineffective in noisy contexts. The proposed pilot study will evaluate taVNS for improving speech in noise perception in adults with age-related hearing loss.

Study arms

  • Experimental
    Treatment A

    participants will receive low level electrical stimulation to the auricular branch of the vagus nerve during the sound in noise task

    Device: transcutaneous auricular vagus nerve stimulation

  • Active comparator
    Treatment B

    Participants will receive stimulation to a control location

    Device: Sham Control

Interventions

  • Devicetranscutaneous auricular vagus nerve stimulation

    active electrical stimulation applied to the cymba conchae of the left ear

  • DeviceSham Control

    electrical stimulation applied to a location on the ear not innervated by the auricular vagus

What researchers measure

Primary outcomes

  1. Speech in noise performance

    Percent correct on a speech in noise perception task in participants receiving Treatment A compared to Treatment B

    Time frame: 2 weeks

Other outcomes

  1. Predictive value of audiometric testing

    Scores on audiometric battery measures and how they differ in those receiving treatment A compared to those receiving treatment B

    Time frame: 2 weeks

  2. Predictive value of brain measures

    Level of baseline GABA levels in primary auditory cortex prior to and following intervention in those receiving Treatment A compared to those receiving Treatment B

    Time frame: 2 weeks

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2025 to primary completion in Oct 2026, 10 months.

Of 25 interventional studies with no phase under Presbycusis, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 58. This study's 10 months is below that.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 20, 2026: primary completion Jul 2026 → Oct 2026 and completion Jul 2026 → Oct 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
