Mycroft created the "happiest room" in the world. 

Microsoft surprised everyone by preparing the "quietest room" in the world.

Individuals cannot visit this room as the company has built it for serious scientific research and product development.

The Guinness Book of World Records has also named it the world's quietest room because no one can stay there for more than a few minutes.

The room is a little more than minus 20 decibels quiet, and as you walk in you can hear your heart beating, then bowel and stomach sound, and then even bone movement and blood flow.

A person sitting in this room for more than 30 minutes will suffer from a strange condition and leave the room

Coming to this room, many people lose their balance and people start fearing even the sound of their breathing.

Special sound-absorbing panels have been installed on the ceiling and around the room by engineers.

It has therefore taken two full years to design and produce.
