Figure 8. If we reduce the horizontal dimension of the source, the

radiation pattern gets wider and starts to spread out (top). The vertical

radiation pattern does not change because the vertical dimension of the

source has not changed (bottom).

If the horizontal and vertical radiation patterns of Figure 8 are combined into a three-

dimensional radiation pattern, the result is waves that are cylindrical in shape. To be more

exact, the radiation pattern is wedge-shaped, or like a piece of a cylinder, as shown in

Figure 9. The shape of the source responsible for this wedge-shaped pattern is slim and long:

in other words, it is line shaped. Thus a line-shaped source where all parts of the line move

with equal magnitude and phase produces a wedge-shaped radiation pattern. The sound

radiates in and out and to the sides, but not up and down.
