Synthesis of localizable sound for the presentation of extra information
Details
Auditory stimulus is an important source of information about surrounding objects. The Sonic-glass is one of the most excellent device that enhances the sound localization ability. However, such a passive methods inevitably provide limited sort of information, and some kind of information, velocity of the objects or concave for instance, are difficult to recognize with sound. Addition of visual information on the natural sound, by the computer synthesized sound, will overcome his difficulty. In this method, however, the compatibility of the synthesized sound with the natural stimulus is critical for inconsistent artificial stimulus may be annoying and, in worst case, even disturb the ordinary localization. In this context, localizable sound was synthesized on a PC and it's compatibility with natural sound was examined.
