Peace is all we want and silence is the best medicine to achieve that. The sound or loudness in a place is measured in decibels (a degree of loudness) and usually the decibels at different places are:
| Places | decibels |
| Aircraft carrier deck | 140 |
| Quiet suburb, conversation at home. Large electrical transformers at 100 feet. | 50 |
| Library, bird calls (44 dB); lowest limit of urban ambient sound | 40 |
| Quiet rural area | 30 |
| Whisper, rustling leaves | 20 |
| Breathing | 10 |
| World’s Quietest Place Yet ? | -20.3 |
Yes, the world quietest place decibel level goes down to negative 20.3, this means that when you are inside the room you can even hear your organs working, quite insane. This is place where noise die.
Microsoft has built this silent room called an “anechoic chamber,” and its located in building 88 in Microsoft’s campus. The reason behind to make this room was to test and improve their devices and Skype call without any disturbance.
