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

894 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?

That’s what you sound like. Not just blood but your organs, gasses trapped inside you, your bodily processes at work. These sounds are always present but are drowned out or unfocused on because of all the stimulation of the outside world. But once there’s nothing left to distract you, you finally hear…yourself. And that’s when you realize silence will never truly exist for you.

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.

Not tinnitus. That is a noise you would hear worse in the ‘quiet’ and loud alongside busy human places. Mine is 24/7 and there is no room for confusion with my other sounds. LPT: try to avoid developing this.

Sometimes we can hear the blood pumping through our veins. sometimes we can hear our own heart. The meatsuit that we each pilot is *alive* and active and has procceses going on all the time, pressure changes in one chamber or area, with gasses and fluids that move around and gurgle or sometimes make a steady hum. Our life is not silent.

In addition to fluids (blood, air, gut gasses) moving in your body, I understand you eventually ‘hear’ the air molecules bouncing against your eardrums (as noise).

Apparently the quietest places on earth (the really-really quiet anechoic chambers) haven’t had anyone able to tolerate staying in one for more than 45 minutes.

humans make a LOT of sounds. We’re squishy, and constantly moving – blood rushing around, lungs filling and emptying and the accompanying sound from the air rubbing on your throat and mouth and nose, heart beating, intestines pulsating, gasses moving around, even the electricity in your brain makes noise.
