sound pressure
Sound pressure is a measure of the variation of atmospheric pressure caused by a sound wave, often measured in pascals (Pa). It represents the local deviation from the ambient atmospheric pressure due to the presence of the sound wave. Higher sound pressures are usually experienced as a higher volume or loudness of the sound. This is the same quantity that a microphone or a sound meter typically measures and is associated with the actual perceived loudness of sound.

Sound pressure
Sound pressure or acoustic pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit for sound pressure p is the pascal. Sound pressure level or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels above a standard reference level. The standard reference sound pressure in air or other gases is 20 µPa, which is usually considered the threshold of human hearing.
