Optimizing a non-invasive method to study auditory nerve function

Optimization of a Non-invasive Electrophysiological Method for Studying the Functionality of Auditory Nerve Fibers

Not applicable Interventional University Hospital, Clermont-Ferrand · NCT04198909

This study is testing a new way to measure how well the auditory nerve works in healthy people to help find hidden hearing loss that regular tests might miss.

What this trial studies

This study aims to optimize a non-invasive electrophysiological method, specifically electrocochleography, to assess the functionality of auditory nerve fibers in healthy volunteers. The research focuses on understanding 'hidden hearing loss,' which may not be detected by conventional hearing tests. By refining the electrode assembly and acoustic stimulation techniques, the study seeks to establish normative values for wave I morphology in individuals without hearing disorders. This could lead to better diagnostic tools for identifying auditory nerve injuries.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy volunteers aged 18 to 55 with normal hearing and no history of ear infections or noise exposure.

Not a fit: Patients with existing hearing complaints, ear infections, or significant medical histories may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive diagnostic tool for early detection of auditory nerve damage, improving patient outcomes.

How similar studies have performed: While the approach of using non-invasive electrocochleography is innovative, similar studies have shown promise in assessing auditory function, though this specific optimization is relatively novel.
