Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m ). One application is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity. Sound intensity is not the same physical quantity as sound pressure. Human hearing is sensitive … WebIn equation form, intensity I is I=\frac {P} {A}\\ I = AP , where P is the power through an area A. The SI unit for I is W/m 2. The intensity of a sound wave is related to its amplitude squared by the following relationship: \displaystyle {I}=\frac {\left (\Delta {p}\right)^2} {2\rho {v}_ {\text {w}}}\\ I = 2ρvw(Δp)2 .
