The sound pressure (RMS) is the most important quantity in sound measurement. Our hearing is a sound pressure receptor, or a sound pressure sensor, because the eardrums (tympanic membranes) are moved by the sound pressure as a sound field quantity. That is the important effect of the excess sound pressure. It is not an energy receiver! When ...

For measurements of sound in water (underwater sound), the reference sound pressure is set as: p 0 (water) = 1 μPa = 0.000001 Pa = 10 −6 Pa (0.00001 μbar), also equivalent to 0 dB. It is important to note the different reference values between measurements made in air and in water.
