Humans localize sounds using a combination of binaural and monaural cues. However, the location of a sound remains ambiguous under many conditions. Because sound localization is often used to guide behavior, representing the uncertainty of a sound’s location is likely to be critical to decisions about where and when to act. However, little is known about whether humans represent the uncertainty associated with a sound’s location and whether any such representations are calibrated to the accuracy of localization. To study these issues, we developed a new class of stimulus-computable models to enable the representation of uncertainty. We optimized the model for sound localization in natural conditions and then compared its uncertainty estimates to those of humans.
