What if silence is in fact a sound, but because its a universal sound we just adapted to it and dont notice it anymore
I actually just wrote a paper on this!!
The short of it is, yes, that's exactly what happens. There's no such thing as pure silence outside of a vacuum (and inside a vacuum you'd be dead). So basically your ears are constantly adapting to the noise threshold of your surroundings and slowly ignoring it. If you were in a perfectly silent room (anechoic chambers are cool!) you would actually start to hear the sound of existing!
Isn't there some room full of sound baffling foam or something that absorbs all ambient noise and most people go mad from the isolation because they start to hear things like their own circulatory system and their heartbeat pounding in their ears?
Ah, there it is. Orfield Labratories in Minnesota. They say the longest anyone's been able to stay inside was 45 minutes, as they could hear their lungs expanding and their digestive system working overtime.
