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 …

Sound pressure p (RMS) as Sound field quantity: The auditory threshold is used as the reference sound pressure p 0 = 20 µPa = 2 × 10 −5 Pa. The threshold of hearing corresponds to the sound pressure level L p = 0 dB at f = 1 kHz. Sound intensity I as Sound energy quantity: The auditory threshold is calculated as the reference sound intensity I 0 = 10 −12 W/m 2. The threshold of …

A reduction of the sound power level of the sound source by 6 dB is resulting in a reduction of the sound pressure level and the sound intensity level at the location of the receiver by also 6 dB, even if the sound power drops to a factor of 0.25, the sound pressure drops to a factor of 0.5 and the sound intensity drops to a factor of 0.25.

http://www.sengpielaudio.com/calculator-distance.htm
Levels of sound pressure and levels of sound intensity decrease equally with the distance from the sound source with 6 dB per distance doubling. There the soundpressure drops to a half and the sound intensity to a quarter of the initial value. The sound pressure p (amplitude) falls inversely proportional to the distance 1/r from the sound source.

L p = sound pressure level (dB) p = sound pressure (Pa) p ref = 2 10-5 - reference sound pressure (Pa) Doubling sound pressure (in Pa) - increases sound pressure level (in dB) with 6 dB (or 20 log (2)). The chart below shows the sound pressure level decibel scale compared to the sound pressure Pascal scale.
