AB  - Wideband absorbers are a fundamental part of non-environment control rooms. They consist of huge angled hanging panels in conjunction with a multilayer wall or ceiling. Their absorption capacity is very noticeable, mostly in the low frequency range. In this contribution, the mechanisms of absorption of the wideband absorbers of the rear wall of the control room at the Universidad de Vigo will be studied. Conclusions will be drawn from the analysis of pressure, velocity volume and intensity measurements performed in the vicinity of the panels, and from the computation of the normal specific acoustic impedance and the normal absorption coefficient.
