1. Consider a speaker at some fixed position, emitting sound uniformly in all directions. You are standing at some distance d from this speaker, holding a sound-intensity measuring device. You then walk 25.0 m in a straight line towards the speaker. At this point you observe that the intensity of the sound has doubled (from the previous location). Determine the distance d. There are no echoes or reflections or interference. 2. You are standing equidistant from four identical jet engines...

(a) Calculate the minimum safe distance (in m) you can be from a speaker that puts out 1.20 W of sound, using the following assumptions. The sound power spreads uniformly over a sphere of radius r and area 4?r2, your eardrum area is 0.720 cm2, and it cannot tolerate more than 1.00 ? 10?6 W. Damage is done by this small amount of power after prolonged exposure and can be repaired by the body, but damage done by 10?4 W...
