Problem 1: What happens, in decibels (dB), when we multiply sound intensity by 10?
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?
Problem 3: If sound intensity changes by -3 dB by what factor does intensity change?
Problem 4: 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):
