## Intensity of sound wave Formula and Calculation

I = E × v/4π × r3

The formula above is obtained by the combination of three other formulae

I = P/4π × r2

P = E/t

t = r/v

## Loudness of sound wave Formula and Calculation

L(dB) = 10 × logE × v × I0/4π × r3

This formula derives from the combination of the two other formulae

### Formula 1

L(dB) = 10 × logI/I0

### Formula 2

I = E × v/4π × r3
