If you're looking for the quietest room on earth, Microsoft's $10 million "silencer room" may be the perfect choice. But it's important to note that no one can stay inside for more than 45 minutes.
Known as the Anechoic Chamber, this room is a small room that is only 21 feet (6.36 m) in every direction. It can ensure that all the sounds cannot come in, and it can also ensure that all the sounds produced are dissolved.
It is reported that this room can block 120 decibels, so even if the jet engine takes off outside, it cannot be heard. The walls, floor and ceiling are covered with huge fiberglass foam wedges that eliminate any echo.

Because the room is too quiet, the sound emitted by oneself will be amplified instantaneously, whether it is the sound of bone friction, the sound of the heart beating, or the grunting sound of gastrointestinal peristalsis, it will be heard clearly.
As early as 2019, a reporter from the British "Daily Mail" visited this silencer room. According to the person concerned, when the door was closed, the sound of his own breathing, as well as the breathing of anyone nearby, became unusually loud. The combination of pitch darkness and complete silence creates a cruel sensory deprivation, a completely unfamiliar, uncomfortable environment.
And after leaving this room, it takes a few minutes to fully re-adjust to the outside world.
