I was hoping to get a pointer to reference to an old auditory localization study that I remember hearing about in an undergrad lecture (my impression was that it was an old study, back when I was an undergrad in the 1990’s), but has stuck with
me all these year because it’s clever and cool.
As I remember it, subjects were seat on a stool within a large cylinder. The walls of the cylinder were made of acoustically transparent canvas or burlap, on which vertical black and white stripes were painted. There was a loudspeaker directly
in front of them, but outside the cylinder so it could be heard but not seen. The cylinder rotated slowly to induce the illusion of motion (subjects felt that they themselves were rotating within a stationary cylinder). When asked where the sound was coming
from, they indicated that it was directly above, the only location in which interaural intensity and timing cues would be constant, if they were indeed rotating.
Assuming I didn’t imagine this study, I’d love to talk about this demonstration with my students, but I need more to go on than my sketchy memories.
Thanks in advance,
Nick
