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 combined level for any two sounds when one is much stronger than the other.
Relevant equations
SIL=10log(I/Io)
I tried to do SIL=10log(70+50) for the first one, but I don't think that's right. Do you divide them instead?
