- Decibel - Wikipedia
The decibel may be defined by the statement that two amounts of power differ by 1 decibel when they are in the ratio of 10 0 1 and any two amounts of power differ by N decibels when they are in the ratio of 10 N(0 1)
- Decibel (dB) | Definition, Formula, Facts | Britannica
A decibel (dB) is a unit for expressing the ratio between two amounts of electric or acoustic power or for measuring the relative loudness of sounds
- What Are Decibels, and How Are They Measured? | HowStuffWorks
Decibels (abbreviated dB) are the units used to measure the relative intensity of a sound The decibel unit of measurement is a little odd because the human ear is incredibly sensitive The human ear can hear everything from your fingertip brushing lightly over your skin to a loud jet engine
- What is a decibel (dB)? - RapidTables. com
Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain Decibel is used to indicate the level of acoustic waves and electronic signals The logarithmic scale can describe very big or very small numbers with shorter notation
- How To Understand The Unit Of Decibels (Simple explanation)
A decibel (dB) is a unit used to measure the intensity or power level of sound or signal It represents the logarithmic ratio between the measured value and a reference value, typically the threshold of human hearing
- Decibel - The Engineering ToolBox
The decibel is a logarithmic unit used to describe the ratio of a signal level - like power, intensity or amplitude - to a reference level Decibel is a dimensionless value of relative ratios The signal units depends on the nature of the signal - can be W for power
- dB: What is a decibel? - UNSW Sites
This example shows a feature of decibel scales that is useful in discussing sound: they can describe very big ratios using numbers of modest size But note that the decibel describes a ratio: so far we have not said what power either of the speakers radiates, only the ratio of powers
- Decibels - HyperPhysics
The factor of 10 multiplying the logarithm makes it decibels instead of Bels, and is included because about 1 decibel is the just noticeable difference (JND) in sound intensity for the normal human ear Decibels provide a relative measure of sound intensity
