Improve speech-in-noise understanding for people with age-related hearing loss

Improving Speech in Noise Perception for Individuals With Age-related Hearing Loss

Not applicable Interventional University of Florida · NCT07192757

This project will try noninvasive ear vagus nerve stimulation (taVNS) to see if it helps adults 55–80 with age-related hearing loss understand speech better in noisy settings.

What this trial studies

This pilot interventional study at the University of Florida will deliver transcutaneous auricular vagus nerve stimulation (taVNS) or a sham control to adults aged 55–80 with normal hearing or age-related hearing loss, including those who use hearing aids. Participants will complete speech-in-noise tests before and after stimulation to measure any changes in speech perception. Key exclusions include prior traumatic brain or noise injury, implanted medical devices or ferrous metal, known heart conditions, and medications that affect neurotransmitters targeted by vagus stimulation. The primary aim is to see whether taVNS produces measurable short-term improvements in speech-in-noise performance compared with sham.

Who should consider this trial

Good fit: Adults aged 55–80 with age-related hearing loss (with or without hearing aids) who do not have implanted devices, significant heart conditions, prior traumatic brain/noise injury, or medications that interact with vagus stimulation.

Not a fit: People with implanted medical devices (e.g., pacemakers), known heart conditions, a history of traumatic brain or noise injury, or on medications that affect relevant neurotransmitters are unlikely to be eligible and may not benefit.

Why it matters

Potential benefit: If successful, taVNS could help older adults with presbycusis understand speech better in noisy environments and reduce social withdrawal.

How similar studies have performed: Small prior studies suggest vagus nerve stimulation can influence auditory plasticity, but using noninvasive taVNS specifically to improve speech-in-noise in presbycusis is novel and remains preliminary.
