While asking about the low frequency decay time of the Neumann KH 420 in another thread, I realized that I had a question about the influence of a speaker's decay time on a room's overall decay time.
Does the decay time of a speaker at a given frequency add linearly to a room's decay time at the same frequency? In other words, if I were to use a speaker with a decay time of 60dB in 200ms at 80Hz, and the room had its own decay time of 60dB in 300ms at 80Hz, would the total measured decay time with that room/speaker system be 60dB in 500ms at 80Hz? If not, could you explain how this works and what the formula would be to calculate the overall decay time?
