Before revision: For speech, the precedence effect disappears for delays above 50 ms, but for music, the precedence effect can also appear for delays of some 100 ms.Blauert, J.: Spatial hearing - the psychophysics of human sound localization; MIT Press; Cambridge, Massachusetts (1983), chapter 3.1 In two-click lead–lag experiments, localization effects include aspects of summing localization, localization dominance, and lag discrimination suppression.
