All share as level the same unit of measure: the decibel (dB). The term "sound level" is commonly substituted for each. As characteristic impedance of air we use the round value Z = 400 N·s/m³ (Pa·s/m). Then the "sound level", that is the sound pressure level L p and the sound intensity level L I is exactly the same as a decibel value. The sound power or acoustic power is the sound …

The absolute sound intensity level, L I, of a sound intensity, I, is defined as: L I = 10 × log (I / I 0) in dB, where I is the measured sound intensity in W/m² (watts per square meter), and the reference sound intensity is I 0 = 1 pW/m² = 10 −12 W/m². Notice: log is the logarithm to the base 10.

the sound intensity by a ratio of 4. In other words, we reduce the sound level by 6 dB. If we increase r by a ratio of 10, we decrease the level by 20 dB. The sound intensity level and the sound pressure levels in dB have the same value, but the size of sound pressure and the size of acoustic intensity is different, because I ~ p 2.
