7. If the acoustic intensity level increases by 6dB, by what factor does the sound (acoustic) intensity increase? What about a 9dB increase? What about a 12dB increase? NOTE: If we know the SPL (Li) or a sound at a distance di, we can work out the SPL (L2) at another distance, d2, from L2-L1 20 log1o
