A Study on Expansion of psycological sound field which makes up Appeal of sound

Abstract

In the past research, spatial impression comes from phase difference between right and left side sound stimulation that is called "stereo effect".We found the result from comparative survey between stereophonic sound stimulate and monophonic sound stimulate. If spatial impression only comes from stereo-effect, we can see significant difference in evaluated value of spatial impression. However, there is no significant difference for them. This result shows us that spatial impression is not only come from stereo-effect.
