Sometimes,
even a little silence is good
for every one of us. But there is a room in USA so quiet that you wouldn’t stay
in for more than 20 minutes. This room is made by Orfield
Laboratories.
The anechoic chamber is behind two heavy doors, encased with
double walls of steal and 30-centimeter thick concrete.
The floor in the room
is made from concrete and fiberglass blocks.
This place is the quietest in the
world. 99 percent of the sounds stays out of the room.
When you enter inside the quiet room, you feel isolated from
the world. In these quietness, the ears start to accommodate to the environment.
You’ll hear your heart beating, and you can even listen to your lungs and you
stomach gurgling loudly.
Inside the quiet room you are actually the only sound-making
object. You are the sound itself that stays in the room.
The longest time that anyone stayed in the anechoic (echo-
free) chamber is 45 minutes.
Staying in that place makes people anxious. Any movement
creates sounds, thus you wouldn’t feel comfortable to move. Many people have
started hallucinating in this room.
The quiet room is used for a lot of experiments. NASA used the
quiet room for space experiments. In many cases the quietest place on Earth is
used for testing sound producing machines and products.
