00:00I'm in one of the world's quietest rooms. You might have seen them in a YouTube video.

00:04So how quiet are they really? I'm probably talking at around 60 dB right now.

00:09Just the sound of you breathing normally is probably around 10.

00:13The quietest sound that humans can hear is set at zero.

00:16But we know that the sound of air molecules moving around is negative 23.

00:22And this room is negative 20.6.

00:26How? It's disconnected from the rest of the building. The whole room is on springs.

00:30And inside, you're walking on mesh above these huge fiberglass wedges that are also all over the walls and ceiling.

00:36Look how deep it is.

00:38The wedges help to trap Soundwave, sending them deeper into the wall where they get absorbed and turned into heat.

00:42It's so quiet in here that I can hear the sound of my own heart.

00:46And then they turned out the lights.
