[QUOTE="Timber_MG, post: 545439, member: 18"] @ Rudi: Toole and Olive have some far reaching research on this among others. If you look at the energy content of the direct sound and its correlation with the first reflections then one does measure this effect easily (see Atkinson's vertical polar plots for a long standing example). If you use an FFT tool like Arta, you can establish this quite simply with a gating that ignores the direct sound. Attie is taking a longer time window than just the first reflections so the power response appears as a trend, though other effects related to the room have a similar say in what he's hearing. One can isolate the power response issue with a set of polar measurements. [/QUOTE]
