SoundSurfer Input

Sound Power Level (red node) OR Sound Pressure Level (blue node)

Algorithm

$L_p = 10log(10^(L_{p1} /10)+10^(L_{p2}/10)+....+10^(L_{pn}/10))$

Output

With Sound Power Level (red node) inputs, output is total Sound Power Level (red node).

With Sound Pressure Level (blue node) inputs, output is total Sound Pressure Level (blue node).
