You have tinnitus.

That's not really tinnitus, I used to have that before I got tinnitus.

Tinnitus is like 30-50 times the volume of that, depending on how rundown I am or whether I have a cold. For me it's predominantly in one ear, though does sometimes change.

What he's describing is fairly normal and is just to do with blood pressure in your ears, from what I've subsequently read.

		A clear example of the No True Tinnitus fallacy. > Tinnitus is a condition when a person hears a ringing sound or a different variety of sounds when no corresponding external sound is present and that other people cannot hear. https://en.wikipedia.org/wiki/Tinnitus

		> What he's describing is fairly normal and is just to do with blood pressure in your ears, from what I've subsequently read. That’s called tinnitus. And I agree, it isn’t rare. From TFA, roughly 15% of people have it (that report it). Sounds like you may have severe tinnitus, which is more rare, limited to 1-2% of people.

		There are different forms of tinnitus, due to there being different causes of tinnitus. Some people even have multiple frequencies of tinnitus at the same time.
