Although tinnitus is truthfully "all in our heads," that does not mean we are making it up. Tinnitus is the brain's attempt to produce sound when less sound (or even none) is coming from the ear. If you look at the American Tinnitus Association website, you can find much good information specifically on tinnitus. For one explanation, see:
http://www.ata.org/for-patients/faqsIf you do a search on tinnitus definition, you will see several good explanations.
I am SSD and yes, I have very annoying tinnitus. I have no inner ear on my AN side so in my case, at least, it is not from damaged cilia. Tinnitus is a brain thing that only we can perceive. I say perceive because it is not noise starting from outside our bodies, but inside our brains. No one knows exactly what I "hear" except by how I describe it. Fortunately, I am able to re-focus my attention whenever I am busy with something, except when I am in an environment with much ambient noise (fans blowing, music playing, many people talking at once, etc.). In those situations it is very difficult to concentrate on individual voices because of the confusion of sounds in my head.
You do not "think you hear it," you
are hearing it.
I have found that my tinnitus is much worse when I drink too much coffee, too tired, and/or too stressed. I try my best to remedy each of those things. I recently resumed my yoga classes and they really seem to be helping me focus my attention away from the noise in my head.
Best thoughts.
