RE: Head-turning sound
Posted by josh358 on March 5, 2011 at 14:06:37:
I remember reading years ago about a study which found that subjects were able to localize sounds laterally with greater accuracy when they were able to move their heads. Also an ad hoc experiment someone tried -- in Stereo Review? -- in which he made a binaural recording with a moving head and then moved his head in unison with the original moves. Or something like that. He reported that it made the image pop into focus. Or, again, something like that -- I read it many years ago.
I've also read that people tend to underestimate distance when they're asked to estimate it. Since we use the percentage and character of reverberation to gauge distance, I guess it stands to reason that we'd be better able to do it indoors than out. To the extent we use parallax and triangulation, I'd also expect it to be easier when the sound source is continuous, though I'm just guessing here.
