Diffusion, with regards to sound control, refers to the distribution by which acoustic energy is spread (diffused) throughout a listening environment.
A sound space that is 100% diffusive has acoustic properties that are evenly spread throughout each listening position.
A sound space that is non-diffusive has wild, but ordered, reverberation that varies throughout each listening position. Essentially, all sound spaces are non-diffusive.
Diffusive acoustical foam treatments keep acoustical energy from grouping together.
This helps to remove “hot spots” or “nulls” and provides a “natural” sense of openness to the listening environment, making it easier to hear “into” the mix.
Diffusive acoustical foam product treatments destroy standing waves and trembling reverberation without removing the original acoustic energy from the listening environment or greatly changing the frequency of the original sound waves.
Since diffusion can make small sound spaces seem larger, it may be ideal to add diffusive acoustical foam treatments, especially if your goal is too increase the amount of “natural” reverberation within a listening environment.
New England Foam fabricates custom acoustical foam products that effectively spread out, or diffuse, acoustical energy resulting in an ideal listening environment.
