That's amazing!
I have pulsatile tinnitus (which sounds similar to what you're experiencing Whiff), which sometimes bothers me. However, my brain then seems to adjust to accommodate it, so it becomes less intrusive.
I had that a few years ago and I went and had a hearing test because of it. But I don’t seem to have it any more. I started going to bed with the radio on because of it, which is something I still do now ( in fact it stays on throughout the night). I’m questioning whether I just imagined it. Or if it just resolved itself.
