An Improved Method for Accurate Sound Localization
When implementing virtual sound systems with headphones, it is well known that using transfer functions other than those of the listener yields front-back confusion in sound image localization. Some studies have concluded that moving the sound image clarifies the perceived location of the sound image. We focus on moving sound images to achieve highly accurate localization, and propose a swing sound image method that makes the sound image swing between two locations on the horizontal plane. Listening tests verify that the proposed method greatly reduces the front-back confusion.
