It can sound like a soft buzzing in one’s ears. Or a sudden hissing. Or a loud roaring. Tinnitus, the sensation of hearing phantom sounds, ranges from annoying to debilitating, and it affects an estimated 10 to 15 percent of the population. Unfortunately, finding relief from these symptoms can be tough.
Doctors and patients may find themselves attempting many treatments for tinnitus, including sound machines to mask the phantom noise, medications to treat underlying anxiety or depression, and investigational brain implants or vagus nerve stimulation. In the United States, there are currently no clinically approved drugs or devices to treat tinnitus.
Now, in a paper published today in the journal Science Translational Medicine, researchers at Dublin-based biotech Neuromod Devices, along with academic collaborators, present positive results from a year-long, randomized clinical trial of a device that pairs sound with gentle electrical tongue stimulation to treat tinnitus. In a group of 326 adults, 12 weeks of treatment with the device significantly reduced tinnitus symptom severity for up to 12 months after treatment.
