Sound Intensity Level Calculator

I want to calculate
Sound Intensity(I) = W
Reference Intensity(I0) = W
Sound Intensity Level(IL) = Db
 

Sound intensity also called acoustic intensity (I) is defined as the sound power Pac per unit area A.

Sound Intensity Level formula

Sound Intensity Level: IL ＝10log10(I/I0)

where I0 = Reference Intensity, I = Sound Intensity, IL = Sound Intensity Level.

For example, when Sound Intensity(I) = 10w, Reference Intensity(I0) = 2W, Then Sound Intensity Level(IL) = 6.9897 Db.
