...To draw the analogy here, you know that there are concave spherical mirrors and concave parabolic mirrors. The better telescopes use the parabolic
type because this type focuses all the parallel light rays at one point while the spherical type doesn't really focus all the parallel light rays at
one point (only the rays close to the principal axis get focused at approximately the focal point.) With that in mind, I see the common familiar
circular bowel design might have an analogous effect in reflecting sound as the spherical mirror, while your current approach might have an improved
effect analogous to the parabolic mirror since the cross section of this bowel may look more like a parabola compared to the familiar bowel circular
cross section... |
