I’m surprised more people haven’t mentioned noise canceling headphones as a possible cause. There was an HN thread about this awhile back. This has been mentioned on many forums, google it.
My tinnitus (from a single loud party), which I had before noise canceling headphones, gets worse with noise canceling headphones, but only temporarily, like 2 or 3 days.
I found out as well that my headphones plays my own voice back to me so that I dont shout, but was able to turn that off in the settings (Jabra 2), which seems to help.
