In my homework, I was assigned a question,
If two firecrackers produce a sound level of 95dB when fired simultaneously at a certain plance, what will be the sound level if only one is exploded ( hint: add intensities, not dB?
My immediate guess is to divide 95 in two, but it seems too simple, plus if it is only one fire cracker, would the sound level be 1/2 ? I don't think I am right, but can someone help me?
thanks
