Sometimes I feel that this is the case, but I've never listened to a
test. There's one Bruce Bartlett did that's cited in the June 2000
Electronic Musician:

... using ten different stereo arrays... Bartlett recorded speech
sources at 0 degrees (center), 22.5 degrees (both left and right of
center), and 45 degrees (also left and right). He did the test
recordings twice: once in an anechoic chamber and again in a
reverberant gymnasium. Afterward, he played [..on headphones?
speakers?]  the results of each miking technique and asked his
listeners to locate the sound sources' positions in the stereo field.

[missing table graphic]

This table shows the averaged test results (the chamber and the gym
recordings, by the way, were very similar). The upper portion shows
the locations of the sound sources (labeled A through E). The bottom
portion indicates where the listeners perceived them to be.

Anyone have this issue or familiar with the results?  Rob D.
