Hi Dave, The paper Blauert cites is by Gardener, M.B (1969) ... this one:
http://asadl.org/jasa/resource/1/jasman/v45/i1/p47_s1?isAuthorized=no (I dont have access to it right now) The abstract says the experiment included the use of both loudspeakers and voices. Blauert's wording suggests he is referring to the results using a real speaker . Maybe you can access the paper and give us more details.
