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.
