AB  - Artificial reverberation is often used to increase reality and prevent the in-the-head localization in a headphone based 3-D sound system. In traditional method, diotic reverberations were used. In this research, we measured impulse responses of some rooms by Four Point Microphone method, and calculated the sound intensity vectors by Sound Intensity method. From the sound intensity vectors, we obtained the image sound sources. Dichotic reverberation was reconstructed by the estimated image sound sources. Comparison experiments were conducted for 3 kinds of reverberations, i.e., diotic reverberations, dichotic reverberations and dichotic reverberations added with Head-Related Transfer Functions. From the results, we could clarify the 3-D sounds reconstructed by dichotic reverberations with Head-Related Transfer Functions have more spatial extension than other methods.
