Two people are talking at a distance of 3 m from where you are and you measure the sound intensity as 9.3 × 10-7 W/m2. Another student is 9 m away from the talkers. What sound intensity, in 10-7 W/m2, does the other student measure? Assume that the sound spreads out uniformly and undergoes no significant reflections or absorption.

The sound level at 1.0 m from a talking person is 60 dB. You are surrounded by five such people, all 1.0 m away from you and all talking equally loud at the same time. The threshold of hearing is 1.0x10-12 W/m2. What sound level are you being exposed to? You can neglect any absorption, reflection, or interference of the sound. Hint: log(A/B)= log (A)- log (B)

Two boys are whispering (one at a time) in the library. The radiated sound power from one boy's mouth is 1.2 × 10–9 W; and it spreads out uniformly in all directions. What is the minimum distance the boys must be away from the librarian so that she will not be able to hear them? The threshold of hearing for the librarian is 1.00 × 10–12 W/m2.
