I dont see any Studies to rule this out Erik, Aldosterone deficiency can be common and can be easily undiagnosed, I support the article as keeping Aldosterone levels topped up can enhance hearing thresholds, this is extremely beneficial for people who have Tinnitus associated with hearing loss.
I totally understand your opinion as I too have questioned this finding as it was discovered in 2008 and I would of thought someone would be shouting about right now, however as you know the discovery was made using Bio Identical Aldosterone, and its quite impossible to get hold of ! unless your associated with a lab or a research Pharmacy!!!, many people used flourinef and it is not the same.
