Recent work has shown that within some limits, listeners can identify
the shape of a sound source (Kunkler-Peck & Turvey, 2000), discriminate
between sound sources of different height-to-width ratios (Lakatos,
McAdams, & Causse, 1997), and discriminate and scale object length
acoustically (Carello, Anderson, & Kunkler-Peck, 1998).
Are you aware of any studies that show how well listeners can determine
the facing direction of a directional sound source (such as a
loudspeaker on a turntable) that is free to project sound in any
direction in the horizontal plane? Short of that is there free-field
localization work in which the loudspeaker does not face the listener
