Outline of Final Research Achievements

For advancement of a virtual auditory display system which can display three-dimensional sound space to both ears, we examined system in order to convolve long impulse responses with high-fidelity in a concert hall. Furthermore, we investigated a process of active listening which includes listener's head movement.
We found some thresholds of a sound would increase in active listening process. We also developed a novel virtual auditory display system, which can process over-three-second impulse responses within a detection threshold of system delay.
