A man stands at the midpoint between two speakers that are broadcasting an amplified static hiss uniformly in all directions. The speakers are 27.9 m apart and the total power of the sound coming from each speaker is 0.450 W.
(a) Find the total sound intensity that the man hears when he is at his initial position halfway between the speakers.
W/m2
(b) Find the total sound intensity that the man hears after he has walked 4.5 m directly toward one of the speakers.
