The noise heard is described as ringing, rustling or whistling, but, in all likelihood, what you have is tinnitus. I have suffered from tinnitus for many years. At first I believed it meant a curtailment of my interest in hi fi. It doesn't, but it is annoying. You should go to a specialist only to be sure that what you have is subjective tinnitus and not a sign of some more dangerous underlying condition. One good sign that it is only subjective tinnitus is if the noise you hear is centred in your head and not on one side only. There is no cure subjective tinnitus, but many ways to manage its effects.
Good luck.
