Hi, I am having a really tough time with question number four on the Owl homework due tonight. does anyone have any suggestions, I keep getting ridiculous numbers from my calculations!

Hi Vanessa,
Can you be a bit more specific about this problem? What particular part are you stuck on?

For problem 4, I would translate each SIL into an intensity ratio. That will give you I1/I0 for SIL1 and I2/I0 for SIL2.
To find the combined SIL, first add the intensities (relative to I0) is OK: (I1 I2) / I0 is the same as (I1/I0) (I2/I0).
Once you have that new intensity ratio (I1 I2)/I0 you can look up the corresponding SIL in dB.
Remember that an intensity ratio of 10 corresponds to 10 dB, a ratio of 20 corresponds to 20 dB, etc…
