Figure 7. As we look down on the plane-wave source, we see that the

sound is confined to the width of the source (top right). If we look from

the side, the sound is confined to the height of the source (bottom

right).

Again looking down on the source, now imagine that the horizontal dimension of the

source (currently one meter) was reduced to only a few centimeters. The result is shown in

Figure 8. The vertical radiation pattern does not change because the source retains the same

vertical dimension (bottom of figure). The horizontal radiation pattern (top of figure) changes

drastically because the much smaller source size corresponds to a much wider radiation

pattern. (Note that the same physics explain why a 2" (5 cm) driver has a much wider

radiation angle than a 12" (31 cm) driver, assuming both are operating at the same

frequency).
