Aural rangefinding

Research team led by GSN/MCN Speaker Benedikt Grothe has shown for the first time that, in humans, the neuronal circuits involved in sound localization are context sensitive


Benedikt Grothe and his research group study the neuronal processing mechanisms that enable the mammalian auditory system to localize sounds in space. In their latest study, the researchers take a closer look at the impact of context on sound localization, and demonstrate that the human hearing system is capable of dynamically adjusting its response when stimuli are presented in sequences. The results question the conventional view that the system primarily serves to localize sound sources with very high precision based on physical differences between the same sound as perceived by the two ears. “Our study will lead to a paradigm change in the understanding of spatial hearing,” Grothe states. The findings appear in the online journal Scientific Reports.
