Inverse Law

If sound intensity increases by a factor of 20, it increases 13 dB. Show an alternate way to derive the decibel (dB) increase (beyond simply using the formula from problem 1).

Problem Assignment Problem 1: What happens, in decibels (dB), when we multiply sound intensity by 10? Your answer here: the sound intensity changes by ______dB Write down the equation that shows how this works Problem 2: If we quadruple (multiply by 4) the intensity of a sound, what is the change in decibels? Your answer […]
