Eli5: what is the noise you can hear when it’s utterly quiet?

890 views

I don’t think it’s tinnitus though all the Google results I got were about it. Last night my partner and I went out into the desert to stargaze, and when there were no cars nearby, we both experienced a constant quiet noise. It’s a hard noise to describe–not a ringing or a whooshing noise, but almost a pulsating kind of noise. Is it the sound of blood going through your ears? Brain making up noises to fill the gaps?

Yes, either tinnitus, or sounds from your own body – the blood moving inside you, your own heart, the sounds of yourself breathing.

The structure of bones in your ears have muscles that contract to limit the amount of sound that enters your ears. In very quiet environments they fully relax, and it is surprising how much you can hear when they do.
