Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave.In air, sound pressure can be measured using a microphone, and in water with a hydrophone.

The sound pressure p is the sound pressure that is specified as an rms value and of the static pressure p St (air pressure) of the surrounding air is superimposed. p total = p St + p

It is defined as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface." The SI unit of sound power is the watt (W).

The Sound Pressure Level (SPL) in decibels = 20 x the logarithm of the ratio of the sound pressure to the reference sound pressure of 0.00002 pascals.

Have you ever suffered from the noise of the neighbors? SPL(sound pressure level) meter app uses your embedded microphone to measure noise volume in decibels(db), and shows a reference. REMEMBER! Most smartphone microphones are aligned to human voice (300-3400Hz, 40-60dB). Voice calls do not require high-performance microphones Audio guru and Altec Lansing consultant Robert Heiblim explains.

The sound pressure falls to 1/2 times (50%) of the initial value of the sound pressure. The sound pressure decreases with the ratio 1/r to the distance.
