Sound - sound - sound pressure sound intensity ...
http://www.sengpielaudio.com/SoundSoundSound.htm
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. For measurements of sound in water (underwater sound), the reference sound pressure is set as: p0(water) = 1 μPa = 0.000001 Pa = 10−6Pa (0.00001 μbar), also equivalent to 0 dB.

Reference sound power Pac0= 10−12W≡ 0 dB-SWL Sound power is neither room dependent nor distance dependent. Direct conversion of sound pressure to sound intensityand vice versa Simply enter the value to the left or the right side. The calculator works in both directions of the ↔sign.

The auditory threshold is used as the reference sound pressure p0 = 20 µPa = 2 × 10 −5 Pa. The threshold of hearing corresponds to the sound pressure level Lp = 0 dB at f = 1 kHz. Sound intensity I as Sound energy quantity: The auditory threshold is calculated as the reference sound intensity I0 = 10 −12 W/m 2.
The relation of sound quantities references and levels ...
http://www.sengpielaudio.com/calculator-soundvalues.htm
The reference sound pressure is p0 = 20 µPa = 2 × 10 −5 Pa − the reference sound intensity is I = 10 −12 W/m 2. Sound pressure is not intensity Differentiate: Sound pressure p is a " sound field quantity " and sound intensity I is a " sound energy quantity ".
SPL sound level to dB pressure level sound pressure …
http://www.sengpielaudio.com/calculator-soundlevel.htm
The reference sound pressure is p0 = 20 µPa = 2×10 −5 Pa. The reference sound intensity is I0 = I0 = 10 −12 W/m 2. DAGA and also DIN request the indication of the sound level in dB alone. The attached SPL comes from the United States and is frowned by acousticians. The often used term " intensity of sound pressure" is not correct.

p is the root mean square sound pressure, p 0 is the reference sound pressure, 1 Np is the neper, 1 B = (1 / 2 ln 10) Np is the bel, 1 dB = (1 / 20 ln 10) Np is the decibel. The commonly used reference sound pressure in air is. p 0 = 20 μPa, which is often considered as the threshold of human hearing (roughly the sound of a mosquito flying 3 m
