title: Enhanced auditory spatial performance using individualized head-related transfer functions: An event-related potential study.
abstract: This study examined event-related potential (ERP) correlates of auditory spatial benefits gained from rendering sounds with individualized head-related transfer functions (HRTFs). Noise bursts with identical virtual elevations (0°-90°) were presented back-to-back in 5-10 burst "runs" in a roving oddball paradigm. Detection of a run's start (i.e., elevation change detection) was enhanced when bursts were rendered with an individualized compared to a non-individualized HRTF. ERPs showed increased P3 amplitudes to first bursts of a run in the individualized HRTF condition. Condition differences in P3 amplitudes and behavior were positively correlated. Data suggests that part of the individualization benefit reflects post-sensory processes.
