Does anyone have a good resource for determining audibility loss (dB loss) through various door types? I recall seeing a reference chart that was perhaps printed in a fire alarm handbook in the 90's, but I don't have a copy.
Intelligibility is a world all on it's own - if we need intelligibility I typically locate a speaker on the opposite side of closed doors (private offices, for instance). Is there a way I can model or predict intelligibility through closed doors? I've tried Ease EVAC years ago using door gaps, but it wasn't well suited to model the losses at that time.
