What is the quietest place on Earth?

The quietest place on Earth is an anechoic chamber, a room designed to eliminate all external and internal sounds. There are two notable anechoic chambers frequently cited as the quietest:

1. Orfield Laboratories in Minnesota: This chamber is so silent that the longest anyone has been able to bear being inside is 45 minutes. It is so quiet that you can hear your own internal sounds, like the blood pumping through your veins and your heart beating, which can drive people crazy 1.

2. Microsoft's Campus in Redmond, Washington: The anechoic chamber here records a noise level of over -20 decibels. It is so quiet that people can hear their own breath, heartbeat, and bones creaking. No one is able to stay in the chamber for longer than an hour due to the extreme silence 2.
