Electric shocks to the tongue can quiet chronic ringing ears
As an aside, I am noticing a correlation to using my noise-cancelling headphones and ringing in my ears at the end of the day. Not even using them for that long - perhaps just 2 or 3 hours total spread out across the working day at "normal" volume levels for meetings (not even music)Cut out wearing QC35s for a day or two and the ringing goes away at night.Do noise-cancelling headphones from the likes of Bose et all "collapse" the sound waves via interference so that the sound waves that do reach my ear are physically lesser, or is it just merely masking noise with anti-noise, and so now I get twice the noise energy pumped into my ears even if I cannot actually hear it as much?
