(Color online) Mean (24 listeners) rms errors in degrees as a function of the eleven loudspeaker locations (2: −75° right, 7: 0° center, 12: 75° left). Left figure: Data for the 2-octave wide filter conditions (CFs of 250, 2000, and 4000 Hz). Right figure: Data for the 1/10th octave filter conditions (CFs of 250, 2000, and 4000 Hz). Data are averaged over duration, overall level, and listeners. Error bars are ± one standard deviation.
