Question
Decibels are denoted by _______.
-
λ
- Π
- A
- Db
Hint:
Decibel: SI Unit of the Sound
As this energy can be measured, then the most common SI unit of sound which is used is the Decibel
The correct answer is: Db
- Decibel: SI Unit of the Sound
As this energy can be measured, then the most common SI unit of sound which is used is the Decibel and it is abbreviated as dB. This unit is generally used to express the ratio of some value of the physical property to another
- decibel (dB), unit for expressing the ratio between two physical quantities
