Proposed move
[edit]I think this is more usually called the "zonal cavity method" because of the cookbook of factors based on room geometry. This needs some tables to illustrate the concepts, and a good description of the limitations. Does anyone still use this method, now that computers are cheap,good, and plentiful? And how about some *history* of the method? Who invented it,who promoted it, when did it start up (I'm guessing sometime after flurorescent lamps got popular)? --Wtshymanski (talk) 15:55, 17 February 2010 (UTC)
