Acoustic diffusers 1D
1D diffusers operate in 180 degrees in one plane (horizontal). The range is related to the scattering geometry of the system.
Lower frequency range corresponds to the depth of the slot and higher frequency – its width.
Number of wells of the diffuser has an impact on the diffusing factor – the more slots means better.
The terminology in the name
The first symbol before the slash indicates number of so called wells.
The second symbol after the slash indicates the approximate width of the body in centimeters.
Additional word basic means budget version (with a thinner frame made with plywood instead of wooden).
Example: 43N 1/120 basic = 43 +1 wells / width of 123 cm, a budget version
