I can hear this ringing all the time, even during a conversation or on the street. I tend to not be aware of it, but when I am, it is ringing loud and clear.

I too tried to describe it - like a waterfall, like the sound of the cathode ray TV set, like the sound of pressured gas escaping from a hole, or just pure sonic pressure. The location of the sound is not in any of the ears but inside the head. When I yawn or when I breath out slowly on the mouth it becomes more intense.

I find it comforting and don't mind it. I even used it as support in meditation (it's called the "nada resonance" in yoga). It's just with me, and has always been. When I found out that not everyone hears it, I was quite surprised.
