I have permanent tinnitus and have this too, though it very rarely happens on its own. When it happens, for me, this sound is usually a signal to immediately change my posture when sitting in a chair.
When I reach flow, I tend to not notice until later that I'd now be sitting cross-legged, or that I've tucked one leg under myself.
That pressure tends to trigger the sound you describe after a while. I imagine because of bad blood circulation, though I have no idea why it's that sound signalling that for me.
