Introduction to Alternating Prime Number diffusers
In modern studio design acoustic diffusers are used to control wall reflections and create a smoothed sound to make it easier for the mixing engineer to judge the sound of a recording. A common method to define the size of the wells is the QRD-Algorithm leading to a so called Schröder-diffuser. Here a different method is used:
Prime values are used for the lengths of the wells and place at alternating / opposite positions like shown in the image below. This guarantees that all relevant lengths are covered and no additional elements / fins are necessary to separate the wells from each other.
Conclusion and Summary
Prime numbers with alternating positions can be used to obtain an alternative kind of sound diffusers.
