Sound Intensity in Relation to Distance Calculator

Posted by Dinesh on

Online sound power calculator to calculate sound intensity in relation to the distance.

What is Sound Intensity?

Sound intensity describes the rate of energy flow through a unit area. In the SI system of units the unit area is 1 m². And hence the units for sound intensity are Watts per square metre.

Sound Intensity at Far Distance Calculation

Formula:

I 2 = I 1 · r 1 2 r 2 2

where,
I₁ = The sound intensity at close distance r₁
r₁ = The close distance from the centre of the source
r₂ = The far distance from the centre of the source
I₂ = The sound intensity at far distance r₂
