Hi I was trying to find my tinnitus frequency by matching different frequencies. When I came across mine , after playing it for a few seconds, I couldnt hear my left ear ringing anymore. I tried it again and again, closed my ears to see if its not a mistake but it was happening. It was temporary and right now its been 20 mins since that , my ringing is really less. I wanted to know why this happening ? Is this a good sign ? If yes , what can be done using this to treat the ringing?
