Bel or decibel.
yes it is a unit of loudness
Loudness of sound: Loudness is that characteristic of sound by which we can distinguish between a loud and a faint sound.It depends upon amplitude, area of vibrating body, intensity and condition of ear. Intensity of sound: Sound energy flowing per second through a unit area held perpendicularly to the direction of sound waves is called the intensity of sound.Its unit is W/m2.
Just like any other substance in existence, the magnitude of sound or loudness can also be measured. In this case, the standard unit of measurement for loudness is called decibels.
loudness
The most common unit of sound loudness is the decibel (dB).
The loudness of sound is measured using the "decibel" or "bel" unit.
Decibels
Decibel
dicibels is the unit that measures the loudness of sound.
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
it is a respect for our culture and nation :)
decimals
Bel or decibel.
The word "volume" represents the relative "loudness" of a sound. The word "decibel" is a unit of measurement for sound.

The unit of relative loudness is the sone. The unit for absolute loudness, or loudness level, is the phon. Both relative and absolute loudness are perceptual measures that vary from person to person.The unit used to measure sound pressure is the dB (decibel). Since dB measures the power of a sound wave, a physical characteristic, it is not a perceptual measure but a scientific one (thus perception of the sound has no effect on it).Read more: What_is_the_unit_of_relative_loudness
