Two people are talking at a distance of 3.4 m from where you are, and you measure the sound intensity as 1.0 10-7 W/m2. Another student is 4.2 m away from the talkers. What sound intensity does the other student measure? I just don't know how to start this problem

power decreases as the square of distance.

calculate the intensity level at the original distance, then

Level2=level1-20log(3.4/(3.4+4.2))
