(a) I = 10−10 watt per m2 (quiet room)
(b) I = 10−5 watt per m2 (busy street corner)
(c) I = 10−8 watt per m2 (quiet radio)
(d) I = 10−3 watt per m2 (loud car horn)
Use the following information for determining sound intensity. The number of decibels β of a sound with an intensity of I watts per square meter is given by β = 10 log(I/I0), where I0 is an intensity of 10-12 watt per square meter, corresponding roughly to the faintest sound that can be heard by the human ear.
