okay yes that makes much more sense, but how do I solve it? Do i replace Io with the W/m^2 number? Ex for 70dB=10log(I1/Io) : Io-10^-12 and I=10^-5? and then just add the two answers together to create the combined sound in each case?

No, your equations don't seem to make sense to me...?

Consider a fixed sound of intensity level SIL1 = 70 dB and another (of different frequency) whose intensity level takes on the series of values SIL2 = 50, 60, 70, 80 and 90 dB. (a) To the nearest dB, what is the level of the combined sound in each case? (b) Make a general statement about the...
