8. The Science Lab: the (Artificially) Quietest Place on Earth
There is silence and then there’s silence. This Minnesota-based laboratory blocks out a whopping 99.99% of all sound. It’s so quiet that you have to sit down, because the sounds you make when you’re moving are blocked out and make it difficult to balance. The longer you’re in there, though, the more you can hear your body’s internal workings: your heart beating, your stomach gurgling, maybe even the sound of your lungs. As cool as that sounds, visitors to this anechoic chamber find it deeply unsettling. In fact, the longest anyone has ever lasted in the chamber was 45 minutes. Your brain begins to hallucinate sounds afteer some time in such utter silence.
