Hi everyone,

I bought my son a new calculator yesterday. He needs to use the INV button, but this model doesn't have one. Anyone know how this is used with the above model? I've googled searched for ages and came up empty handed. Any help would be greatly appreciated.

Thanks a bunch,

JoJo

As in inverse square.
Example for sound.

If the distances from the sound source are d1 and d2, then the difference Dd in dB at these points is: Dd = 10 log (d2/d1)2 = 20 log (d2/d1)
