The unit is the decibel, based on a larger unit called a bel. The decibel is measured as a magnitude on a logarithmic scale, and has no dimension as such. An increase in the numerical value therefore indicates an exponential (logarithmic) increase in the actual intensity or power.
Example : an increase of 3 dB is approximately twice the power, an increase of 10 dB is 10 times the power, and an increase of 20 dB is 100 times the power.

Unit of measuring loudness of sound is called?
The unit of measuring loudness of sound is called the decibel (dB). The decibel scale is logarithmic and is used to compare the intensity of different sounds.
What is SI unit of measuring pain?
There is no standardized SI unit for measuring pain. Pain is subjective and therefore difficult to quantify using a single unit of measurement. Instead, pain intensity is often assessed using scales such as the visual analog scale or numerical rating scale.

What is the Unit of measuring the intensity of sound?
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
