Thus far I have made a couple of binaural recordings of (1) a perceiver walking past individuals reading text (live) and (2) a perceive= r walking past a series of loudspeakers projecting an assortment of recorded sounds (e.g., human speech, typewriter clicks, etc.). Those who have listened to these recordings have found the first set a much more compellin= g indication of the listener=B9s motion than the second. There are several reasons why this may have been the case: the live readers were fewer, more sparsely located, and generally louder than the recordings via loudspeakers= . I am writing to the list because I was hoping that some of you might have some intuitions or know some references that would help guide me to more successfully capture the acoustic flow field of a person walking through a hallway. Specifically I am wondering whether live sounds should b= e easier to localize through a loudspeaker than recorded sounds? Furthermore should the localizability of the sound sources contribute to the =8Crealness=B9 of the walking event for a listener? I would greatly appreciate any thoughts on this issue. > Respectfully, > Mike Gordon --=20 Michael S.
