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

884 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?

Just a reminder that top-level comments (those are comments that are a reply directly to the post itself) must be explanations for the question.

Anecdotes and tangents are not allowed.

If I remember correctly, I read that your brain creates sounds during absolute quiet to keep its self alert.

There are a few instances of people going into quiet rooms in recording studios for challenges and slowly going crazy because of lack of ambiance noise.

You’d know if it was truly tinnitus, because it almost hurts at times. It’s a ringing sound, buzzing like sound that really affects you, it’s nearly constant and would affect your daily life. (Trust me, I have Meniere’s and tinnitus). Sounds like you both just fully got some quiet and heard body sounds. But if you are worried, check in with your GP. Never hurts to ask your doctor.

With it being the desert, its nightlife can have a wide range of sounds…particularly if in the distance being carried through the cold air.

Not to discount other answers, merely havent seen this response yet.

There’s a phenomenon called “the hum” that some people report experiencing, it’s not really a single proven thing but you could read more about it if you’re curious and see if any of the explanations line up for you.

In addition to other answers, you can often hear the hum of small electrical transformers when you have stuff plugged into outlets.

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.
