It is one of three equations that were used by the BBC for evaluating spaces for possible use as control rooms. It's also given in both of the documents I mentioned: BS.1116-3 and Tech.3276. The original source appears to be an earlier paper by Walker, but I can't find it right now.
For followets of this forum and not jerks, attached is the originating document.,
