In the past three years, I used PSI AVAA to decay low-frequency energy, and I am very satisfied (except for the price).
In Comsol simulation, the value of the AVAA working surface impedance can be estimated at 120 Pa*s/m between 15 and 150Hz.(be modelized by a ¼ of cylinder of approximately 50cm tall and 20cm diameter.)
The research paper, Low frequency absorption by velocity control through acoustic resistance
FYI.
