Product Description
Diffusion, in general, is the movement of a substance from an area of high concentration to an area of low concentration.
Diffusion, in audio, is the scattering of sound waves, reducing the sense of localization.

A good diffusor not only changes the reflections to propagate in different directions, but does so EVENLY in all directions. Just splitting a wave to go into 2 directions doesn't do enough. We've effectively changed the concentration of the waves in a certain portion of the room. We've also effectively taken the intensity of the initial wavefront and split it among the various reflections so that each one is not only coming from a different direction, but each is also weaker and harder to distinguish but we've lost no energy in the process.
A proper diffusor also impacts the time domain. If we have the same wave and it gets reflected into multiple directions evenly, the length of the path the various waves must take to reach the listener also changes. In the world of sound, distance is time. For ease, we can say that 1 foot equals approximately 1ms of time. So, if we've changed the path into say 8 different paths (in reality, there are many paths but we'll look at 8 just for ease of understanding), each one ideally with have a different path, which means that they'll arrive at 8 different times. Again, we're diluting the concentration of sound but this time in the time domain instead of spatially. In addition, these different path lengths cause differences in the number of reflections and the amount of air the wave passes through which will cause each reflection to have a different intensity (more dilution in yet another domain intensity).
Q: What is the best place for diffusors?
A: This really depends on the situation and what you're using the room for. Diffusion can be used up high in a room to kill slap echo, in the rear of the room along the side walls, in place of absorption on the ceiling, etc. The most common place to see diffusion in a studio environment is on the rear wall. However, many times, you'll benefit more from absorption there to kill a strong bass null off the back wall.
Q: Is it true that you need to have a large room for diffusion to be effective?
A: Again, yes and no (seeing a pattern here? Every room is different). Normally, in a smaller space, one needs proportionately more absorption for bass control than in a larger room. This leaves less space for diffusion not to mention the issues raised in the first question. However, diffusion can still be effective up high in the room to assist in killing slap echo and controlling the 'zing' in a room especially a tracking room.
