Since the PIC/MCC calculation can only track short time scale electric field instabilities because of the limited calculation time, we can conclude that Bohm diffusion is mainly

Such coupled room impulse responses can be synthesized using a recently proposed sound energy decay model based on a diffusion equation and adapted to coupled spaces.. This

The use of real data of the studied operating room (geometry, volume, extracted and blown air flow, temperature and hygrometry) will allow the determination of
