For measurements of sound in air, the reference sound pressure is set as: p0(air) = 20 µPa = 0.00002 Pa = 2 × 10−5Pa (0.0002 μbar) as effective (root-mean square) and the reference sound intensity is I0= 10−12Watt/m². This corresponds to the lower limit of the sensation of human hearing at 1000 Hz, equivalent to 0 dB.

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 …

of the air pressure . p. Reason: The . air pressure and the air density . are proportional to each other at the same temperature. This means in Eq. 1: The ratio . p. 0 / 0. is always constant. The speed of sound in air depends on the density of air and the density of air depends on the temperature. Therefore the speed of sound is the same on a ...

The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavelength of the sound.For an ideal gas the speed of sound depends only on its temperature and is independent of gas pressure. This dependence also applies really good to air, in good approximation and can be regarded as an ideal gas.

The sound pressure level decreases in the free field with 6 dB per distance doubling. That is the 1/r law. Often it is argued the sound pressure would decrease after the 1/r 2 law (inverse square law). That's wrong. The sound pressure in a free field is inversely proportional to the distance from the microphone to the source. p ~ 1/r.
