The Quietest Place on Earth 😶‍🌫️🔇#shorts

[00:00:00]Did you know sound can actually go below zero decibels? It sounds impossible because how can sound be less than zero?

[00:00:06]But the quietest place on Earth measures around -20 decibels. It's a special room built by Microsoft called an anechoic chamber. The walls are covered in giant sound-absorbing wedges that trap almost every echo before it can bounce back.

[00:00:19]And the entire room is built on massive springs [music] to block vibrations coming through the floor, which creates something almost no human has ever truly experienced before, near total silence.

[00:00:29]Here's where it gets really unsettling.

[00:00:31]Once the room becomes quiet enough, your brain starts picking up sounds that are normally drowned out every second of your life. People inside report hearing their heartbeat, their breathing, and even joints moving inside their own body. Some become so uncomfortable in the silence that they can't stay inside for more than a few minutes. So, negative decibels don't mean no sound.

[00:00:50]It means the room is quieter than the threshold of human hearing itself.
