After a few seconds of travel the leading edge of the waveform encounters the branch sticking out of the water. This sets off a waveform moving outward from the frog’s entry point in concentric circles, in all directions (360 degrees). In this pond there is a small branch sticking out of the water, and several feet away there is a frog sitting on a rock. In order to get a good visual image of wave diffraction let’s picture a pond of still water. In fact, most of the early work in diffraction came from the field of Optics, as far back as before Isaac Newton, and as a result we will sometimes use terms like “illuminating” the edge, and a “shadow zone” even when discussing the diffraction of sound waves. All of these diffract in ways that are predictable and consistent. The description is same whether we are discussing light, sound, or waves in the water. Both partial reflection and diffraction occur when sound waves encounter an obstacle in its path. This is in contrast to the much simpler phenomenon of reflection, which leaves the waveform shape intact. What is Diffraction?ĭiffraction is the name given to the “bending” of waves (distortion of wavefronts) produced when they interact with objects that are comparable to a wavelength in size. In this article I will attempt to clear some of the fog on the topic of cabinet diffraction, and hopefully, present it in such a way as to make it much easier to understand. Diffraction, acoustic phase, and how listening rooms impact our reproduction of sound, based on what I see posted in many discussions on the internet, are subjects of much confusion. One of the most misunderstood topics in audio is the subject of diffraction.
