Hello Junfeng We cannot perceive the distance regarding the sound source directly. The both receptors for sound, differently the eyes, are dedicated for perceiving the direction regarding the source, not the distance. Thus, we must rely upon natural Stimul, stored by listening experience in our mind.
Unfortunately, that detection is very difficulty. Especially, if we don't know the genuine sound of the source, we can estimate the distance only very crude. Moreover, if the playback room spends considerably own reflections at the signal, the correct estimation regarding source distance becomes nearly impossible, especially for proximate sound sources. Thus, the description of the formidable deep impression of any loudspeaker reproduction seems doubtful in my view.
