Explanation:
Detailed explanation-1: -vacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there. It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal).
Detailed explanation-2: -Some vacuums make quite a racket, especially when running at full power. But there are also ones that do a pretty good job of keeping the noise level down without sacrificing performance. In CR’s vacuum lab, we measure sound with a decibel meter at ear level with a vacuum set to deep-clean at its maximum power setting.
