Reduced Localizability in Sequences of Narrowband Noise Bursts

The precedence effect describes perceived localization dominance of a sound event over a sound event arriving 2 to 50 ms later. A related effect, occurring with sequences of 100 ms long narrowband noise bursts, is described. In contrast to classical precedence effect experiments with two sound sources, the noise bursts are emitted from three frontal positions. Depending on the length of pauses inserted into the sequence, the center source is significantly less localizable than the side sources. An equivalent experiment with only two source positions, similar to precedence effect experiments, does not show reduced localizability. Some of the results can be explained with the cue selection model (Faller and Merimaa 2004).
