Spatialized Sound

Audio that is rendered with positional information so that it appears to originate from a specific location in three-dimensional space around the listener. Spatialized sound uses techniques like head-related transfer functions (HRTFs), interaural time differences, and interaural level differences to create the perception of sound sources at particular positions. In accessibility applications, spatialized sound enables blind users to build mental maps of virtual environments, navigate physical and digital spaces, and understand spatial relationships that sighted users perceive visually. Research has shown that spatialized sound can improve memory and comprehension compared to non-spatial audio presentation.
