Hello Junfeng, it's no easy task to evaluate distance perception under anechoic conditions (which obviously hardly exists). We did this during my PhD research on WFS. Have a look at our paper:
Wittek, H., Kerber, S., Rumsey, F. and Theile, G. Spatial perception in Wave Field Synthesis rendered sound fields: Distance of real and virtual nearby sources Preprint #6000, AES 116th Convention, Berlin, 2004 or my thesis on my website: http://www.hauptmikrofon.de/ Good luck, best regards, Helmut Wittek >>>-----Ursprüngliche Nachricht----- >>>Von: sursound-boun...@music.vt.edu [mailto:sursound-boun...@music.vt.edu] >>>Im Auftrag von Junfeng Li >>>Gesendet: Sonntag, 17.
