The Effects of Early Decay Time on Auditory Depth in the Virtual Audio Environment

To provide the distance information of the sound source in 3-D audio environment, we must have some information about effective distance cues and some methods to handle them properly. Through our experiments and researches, we found that C80 and EDT change systematically with source-receiver distances. We are required to validate this result physically and psychologically. So, this paper contains physical explanation about two parameters' systematic changes and psychological tests with artificially controlled curves, which imitate different distances. With these validations, we want to show the effect of early decay time on auditory depth.
