Problem C16: Two speakers are producing sound as shown below. The two speakers are independent of each other (i.e. incoherent sources), and the sound is radiated isotropically in three dimensions. The amplitude of the diaphram of one speaker is A0 and it is located a distance R away from a girl. The sound intensity from this source alone that the girl hears is I0. The amplitude of the diaphram of the second speaker is n2A0, and it is located a distance of n1R away from the girl. If both speakers are producing sound, what is the sound intensity that the girl hears? If the sound intensity that she hears is I = n3I0, what is n3? Note that n1, n2 and n3 are unitless.

n1 = n2 = Input n3:
