Do you tolerate ear noise? We were surprised to learn that 15-20% of people have this condition which leads to continuous ringing in the ear. Science does not fully understand the ringing part, but one possible explanation is that the brain slows down for frequencies it can no longer hear.[Hubert Lim], a biomedical engineer at the University of Minnesota discovered that the brain can be stimulated to the point of suppressing tinnitus for up to a year. [Lim] it is discovered inadvertently while doing deep brain stimulation in a patient with tinnitus. The electrode was slightly lost, it touched other areas of the brain and the patient suddenly shouted that they could no longer hear their tinnitus.
Then [Lim] and his group tried guinea pigs, looking here, there, and under the armpit for the best place to suppress ear noise. As it turns out, the tongue is one of the best places when used with a specific soundcape. So they conducted a test on the man with 326 people. Each person has a small paddle electrode on their tongue and headphones on their ear.
As the electrodes flashed like Pop Rocks against their tongues, the test participants listened to pure frequencies played in the background of sound resembling vaporwave music. The combination of the two overstimulates the brain, forcing it to suppress the noise reaction in the ear. This discovery certainly sounds like a game changer for those who suffer from tinnitus. If we have tinnitus, we will be the first in line to try it if given the chance. Using the soundcape, we are left to wonder how many 9V batteries we need to lick to estimate the paddle.
Speaking of taste, have you ever experienced all five at once? Here is a device that simulates them all.
