LEV (Listener envelopment), which corresponds to surround sensation with independent direct and reflected sounds, is the spatial impression in three-dimensional sound field reproduction systems.However, IACC (interaural cross-correlation), which is conventionally used as an objective index to measure LEV, has difficulty in rating the surround sensation as it assumes a time-invariant sound source.In this paper, we propose a new objective index for surround sensation based on differential short-time IACF (interaural cross-correlation function).We evaluated the effectiveness of the proposed method through evaluation experiments.
