(a) I = 1011 watt per m2 (rustle of leaves) (b) I = 102 watt per m2...
Question:
(b) I = 102 watt per m2 (jet at 30 meters)
(c) I = 10−4 watt per m2 (door slamming)
(d) I = 10−6 watt per m2 (normal conversation)
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.
