L stands for level. All levels are measured in decibels or dB. You need a reference, e.g. the threshold of hearing: p0 = 20 µPa = 2 x 10-5 pascals that equals 0 dB.
The loudness or volume of music is measured in decibels. Decibels are a unit used to quantify the intensity of sound.
•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons or a stereo can make up to 80 decibels. Volume is measured in decibels. So Frequency is measured in hertz
