Okay so let me start by saying I have tinnitus in my left ear, have done for yonks, it's like a whine, electrical sound, that bothers me now and then, but lucky enough to have learnt about it before I did any more damage knowing I’m susceptible to tinnitus. But I have this burning question and the internet has no answers apart from “it’s tinnitus!!” When I’m in a quiet room, or even so if the tv is on low, I have head noise in quiet areas. I don’t see it as tinnitus, because to me it’s always been in my ear, but if I focus on this head noise it gets louder. It’s not like any particular sound, almost like an ambient sound, that I wondered what exactly is that? Is it tinnitus or does everybody hear it? Somebody told me about this and they said oh yeah that, that’s the sound of silence. Others have mentioned things that it is blood flowing. (I’m not talking about pulsatile tinnitus). It’s not even an annoying sound, often I won’t notice it during day, in the nighttime in a quiet house I can hear it, sometimes it even distracts me from hearing my usual left ear tinnitus. Do non-tinnitus people even have this? What is it? Or is it actually a component of tinnitus? I must also point out that, if I plug my ears, the sound is barely there - diminishes to almost nonexistent and I can hear my left ear tinnitus perfectly then. @Michael Leigh, do you know anything about this?
