Strange, I could say. But there are stages of quietness within the mind of one. Some say that there is a stage called 'tabula rasa' which is the concluding statement that says at birth, people's minds are filled with nothing, as if there is no innate knowledge, but instead it is gathered throughout the stimuli of the environment that is connected or even relocated throughout the nerves of a person, even at birth. If this is true, then I can see why you would have sounds in your head. I think we all do. A mind is never truly blank, not that I think, anyways. For it is filled with subconscious thoughts and notions that pertain to memory and futuristic desires among other subjects. However, a repetitious sound sounds like something else, but I am no doctor. For I have no reason to diagnose you.
When it comes to noise, it is more like gamma interspersed throughout its audio form. Like a fusion of sound waves. That is like the 'backup' after all, particularly if the mind is busy. The mind can be busy even if it is peaceful, because it focuses on one thing: it may not be thought, but it may be particles that are heard.
