From the developer:
WinFLAG does the job of calculating the absorption coefficient, the impedance and the sound reduction index for constructions combining different material layers such as porous materials (e.g. mineral wool), solid and perforated plates (slotted, with circular holes, microperforated). WinFLAG also calculates the attenuation of noise in ducts, e.g. air-conditioning ducts, lined with the chosen layers.
