Hey there, I took some measurements in a venue I work in recently and am having trouble understanding the EDT times, as some of them seem to be longer than the T20. I've been referring to ISO 3382 and am not entirely sure if I understand the EDT measurement properly. Is the EDT time extrapolated similar to a T20 to reflect a 60dB decay? If so then all is well. If the figure merely describes the decay time for the first 10dB, then I'm confused, as some of these are longer than the T20 in certain octave bands and most of the others are extremely close.
Any thoughts would be much appreciated

Many thanks in advance
