Homework Help: Physics

Posted by Gurudev on Wednesday, March 27, 2013 at 7:55am.

Airplanes are noisy things. For example, if you stand really close to a runway, a military jet can produce a sound intensity of about 100 W/m^2 at a distance of 30 m from the plane (this is beyond painful noise). You live near a military airport and want to work on physics with your friend. Since you don't want to shout, you decide to find a spot far enough away from the airport that the airplane noise is below the threshold of conversation (10^{-6} W/m^2). How far do you need to go from the airport in kilometers to accomplish this?
