Dear List, 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 directly? Thanks, -John Neuhoff References: Carello, C., Anderson, K. L., & Kunkler-Peck, A. J.
