It surprised me too. Not a cure, but it does reduce the buzzing.
I notice that some of the drumming is in about the same place as some of the acupuncture massage points from the second link. I haven’t really tried those but I intend to.
(Massaging or just putting pressure on the indicated areas.)
There are treatments that claim to cure tinnitus. They contain biotin and something that was extracted from oranges. Take B vitamins and eat oranges too, I suppose. There are some other threads that about the same time that this came out that discuss medical treatments, or potential medical treatments.
I tried the acupressure thingy also. On first try it did not do as well as the drumming. Will try again.
As to the biotin and orange stuff, I trust the Tinnitus Assn and they have not said these are effective.
