Mine is similar to what @Raudrive has described (or @haggis no.1), i.e. a constant buzzing like locusts on a summer night. It doesn’t seem all that loud to me, so I cope just fine. Occasionally, when I’m really tired, it becomes louder and more pronounced. It stems from some medication I had to take in the 1990s for a while. Those meds initiated the tinnitus, and even though I’ve not been taking said meds for several decades, the cozy buzzing/humming remains an ever present companion.
The tinnitus “chirps” worried me a bit last week when I was taking an audiogram. Am I hearing an actual tone, or just the noises that live in my ears?
I’ll be interested to see if the new HAs I’m to get in 2½ weeks will have any affect on the tinnitus. Allegedly, some HAs are claimed to help with tinnitus.
