In the case of technology, appearance is not everything. Let’s talk about important things like audio. That’s why Microsoft has set up an international standard audio lab at their headquarters in Redmond, Washington.

Many more important things like personal assistant software Cortana rely on good quality audio. Said Lee Shailey Munro, senior engineer at Microsoft Surface Devices These systems require good quality equipment, from microphones to speakers. And that is why they have created the quietest place in the world. Meanwhile, the Guinness Book of World Records Occupied This chamber.

Here are some pictures of the quietest place in the world

Microsoft Audio Lab’s ‘Encyclopaedic Chamber’ which means completely resonant free that absorbs all kinds of noise.

The big wedges you see here are made of sound absorbing material.

This is a graph of 136 decibels (a) of sound that occurs in a jet plane.

It is a sound of 0 dBA level which is the lowest level of human hearing.

And this is -23 DBA which is caused by the movement of air particles in space.

It is the quietest place in the world before the creation of Microsoft Audio Lab, Orfield Laboratory, Minneapolis, Minnesota. Where the noise level was measured -13 dBA.

And Microsoft broke all previous records Created Rooms with only -20 dBA range.
