AB  - Whereas the aerodynamic effects take a significant place in the behavior of sound sources in the low frequency domain and for signals containing a high specific energy, new complex fluid parameters have to be implemented to take into account possible causes of sound distortion such as the stalling phenomenon in the boundary layer around the mechanical structure. For the design of vented boxes, we show that the choice of a nozzle profile for the resonator ensure a better dynamical stability of the airflow and thus authorize extreme low cutoff frequencies in "dipole" configurations. It will be described some experimental and computed results based on phase spaces and fluid FEM about the radiating output of that kind of source under 40 Hz.
