I gave it a few tries before, but I must be doing it incorrectly or in a less than ideal fashion, as the effect never seem to last more than a couple of seconds for me.
They'd have to actually figure out what causes it to begin with, first. They can look at 100 people that were around loud noises that damage ears and often cause tinnitus, but couldn't tell you why 50 of those people would have ringing, while the other 50 don't. Let alone the people who have it without being around damaging noise. Or how I went deaf in one ear from nerve damage but have no ringing, even though most people who go deaf from nerve damage do have ringing.
So everyone experiences it exactly like you? Come on dude. Ever heard of chronic tinnitus? And what you have sounds like occasional ear ringing. Not everyone is just like you.
IIRC there's a few novel treatments (one using electro simulation of the tongue) and some new studies on the cause of tinnitus (auditory nerve overcompensating) that may lead us towards a cure.
Would have to do some digging to find those sources though.
