The precedence effect encompasses several phenomena that influence sound perception and localization when multiple sound sources arrive at the listener in close succession (Brown et al. 2015; Litovsky et al. 1999). For a range of delays between a leading (i.e., first arriving) and lagging (i.e., later arriving) stimulus that arrive from different directions, receivers tend to perceive only a single sound source, a phenomenon known as fusion. When leading and lagging sounds are presented simultaneously or at extremely short delays, a single fused sound is perceived, but the sound’s location is perceived to be somewhere in between the actual location of the two sound sources, a phenomenon known as summing localization. At longer delays, receivers tend to perceive this fused sound as originating from the location of the leading sound source, a phenomenon known as localization dominance. Finally, as the delay between leading and lagging...
