It will probably reduce over time. It requires patience which is hard with noise in our ears! Doctors don't have much to offer other than "put it on the back burner." The brain does adjust and the noise goes into the background of your awareness.

Given the cause, I am also wondering if yours is temporary.

Often hearing loss is a trigger: the brain tries to fill the void with noise- or at least that is what docs have told me. It sounds like yours was triggered by changes in air pressure so hoping it is there for just a short time.

ps I hear mine now because I am writing about tinnitus!!
