There are two: the bel, or more commonly, the decibel, which is a logrithmic representation of the pressure of a sound, and the phon, which is a measure of how loud a sound is perceived.

60% of 188= 60% * 188= 0.6 * 188= 112.8
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".

The decibel level considered too loud for dogs is around 90 decibels.
Sound is measured in Decibels. This is judged based on the human hearing. You can use a decibel meter to detect just how loud a sound is.
A Zymbal is a musical instrument.... Decibel is a unit of measurement for how loud its sound is :-)
A decibel meter is used to measure sound. It is a handheld device and can be used to quickly measure how loud certain sounds are. They are sometimes used to measure how loud a crowd is in sports.

Decibels are the measure of how loud something is.
120 decibels is the sound of a jet engine, or the volume of loud rock music at a concert.
'decibel' means power level compared to something else. +36 dB = 3,981 times as much power as whatever it's compared to.
Sound is measured in Decibels. This is judged based on the human hearing. You can use a decibel meter to detect how loud a sound is.
Audio engineers talk about the "JND", which stands for "just notiecable difference", which is a 3 decibel gain. That 3 decibel gain requires a doubling of amplifier power. For an amp to sound, subjectively, "twice as loud" requires a tenfold increase in power (300 watts instead of 30 watts).The decibel scale is logarithmic, not arithmetic.
All I can think of that you might be asking is what is it measured in, and that would be the unit of the decibel (dB)
