Tinnitus affects 10-15% of the population worldwide, and can be described as a debilitating condition which can push individuals to the limits of their tolerance. As a tinnitus sufferer, resulting from my time in the Royal Marines, I have always been interested in research to help those who have to endure the constant noise that circulate their heads.
In October 2020, the largest research study in the tinnitus field was conducted, recruiting 326 participants. Researchers looked into the effects of combining sound, and electrical stimulation of the tongue (bimodal neuromodulation). Wireless headphones delivered sequences of audio tones layered with wideband noise to both ears, combined with electrical stimulation pulses delivered to 32 electrodes on the tip of the tongue. Participants were instructed to use the device for 60 minutes each day for 12 weeks. Participants were assessed at three follow-up visits for up to 12 months. More than 66% of those who used the device benefited, and 77.8% said they would recommend it for those suffering with tinnitus. It was reported that therapeutic effects can be sustained for up to 12 months post-treatment.
