Acoustic and Electrical Stimulation for the Treatment of Tinnitus
NCT03511807 · View on ClinicalTrials.gov ↗
Study Summary
Tinnitus, or ringing in the ears, affects 10% to 30% of the population. Of those, 20% have tinnitus bothersome enough to seek medical attention. In many people, tinnitus can significantly affect the quality of life. At this point in time, there is no effective treatment or cure available for tinnitus. It has been found that electrical stimulation of the inner ear can reduce and in some cases eliminate tinnitus. The purpose of this research is to investigate both acoustic and electrical stimulation of the inner ear as a possible treatment of tinnitus. In both acoustic and electrical testing conditions, the subjects will be instructed to be familiar with a 0-10 ranking scale of loudness. In acoustic testing, the stimulus will be presented through headphones in a noiseless environment, and the subject will be asked to report on the loudness of the presented sound and the level of the tinnitus at 20-second intervals. If the subject cannot perceive the presence of the tinnitus, a value of zero will be assigned. A typical sound will be presented for 3 to 6 minutes. Loudness will be reported for 1 to 4 minutes after stimulus offset to measure the presence and duration of residual inhibition. Electrical stimulation will be delivered to the inner ear in three ways, 1. using a cochlear implant (implant placed in the inner ear to replace hearing function), 2. Using an electrode placed in the ear canal, and 3. using a small needle inserted through the ear drum. Various electrical signals will be used to evaluate the reduction in the tinnitus perception by the subject. The subjects will rate the loudness of the tinnitus before, during, and after the electrical signal. Surveys will be used to evaluate the tinnitus loudness and the quality of life of the subjects. Hearing tests will be used before and after the procedures. The long term goal of this research is to develop a device to treat tinnitus in people who can hear and to develop programs for cochlear implants that help t

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03511807
The ClinicalTrials.gov registry entry for NCT03511807 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 100 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, Irvine, which has 353 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Tinnitus appearing as the primary indexed condition, and to 2 interventions — of which Electrical is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03511807 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
