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
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.
