avec deux écrans sur chaque tête et analyser le mouvement des aérosols de 3 microns en variant la distance entre les deux têtes. Quelqu’un serait disponible pour réaliser cette simulation pour BTP ? 
merci par avance.

These simulation studies below show the trajectory of particles near the shielded person’s mouth and nose area, as a general reference case. As observed in all the simulations we have run (with different face shield models here), small particles are drawn behind the shield, and the shielded person could inhale those particles.

Therefore, it is to be noted that a face shield/ visor offers an additional layer of protection along with the use of a mask. This is evident from the 2nd & 3rd video below and the accompanying images.
