...Michael S. Reichert; Bernhard Ronacher ABSTRACT Sound localization is fundamental to hearing. In nature, sound degradation and noise erode directional cues and can generate conflicting directional perceptions across different subcomponents of sounds. Little is known about how sound localization...

Recent controversies regarding the mechanisms of sound localization will be discussed. Finally, the case...
