Kersten: Directional Sound Field Decay in Reverberation Rooms
Zoom-MeetingAccording to ISO 345, the random-incidence sound absorption coefficient is measured in a reverberation room by determining the different reverberation times with and without the absorber inserted. The sound field in the room is assumed to be diffuse. Thus, the corresponding energy decay curves would be strictly exponential, but turn out to represent multiple decay […]
