The purpose of this research was to measure hemispheric processing asymmetries for fixed vs. moving auditory stimuli using event-related potentials and psychoacoustic methods. Normal hearing participants were presented with auditory stimuli under headphones that varied by several parameters affecting the perception of sound source position and movement. Results suggest that there are hemispheric differences for fixed and moving lateralized sounds created by interaural level differences. The findings may prove useful in creating clinically useful tests of spatial listening.
