I was just going to, in response to the passage below, suggest Gunther Theile 1985, but then noticed at the end of your post that you had indeed referenced him
"...the brain is able to extrapolate from severely comb-filtered sensory input and gives us the impression of hearing an uncolored auditory event. good luck simplifying that :) i'm looking forward to hearing about your test design..." Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 The key point there, as Gunther alluded to, is that there is a kind of gestalt/auditory scene analysis/cognitive principle that a given signal quality can belong to one schemata or another, but not both. So what the pinnae produce is comb filtering, but it is heard as specific directions - and it is correspondingly hard to introspect on the comb filter characteristic. Gunther showed some ways that you can actually uncover that comb filter, in the course of his demonstrating that a phantom image is not physically equivalent to a real source, even if is perceptually equivalent (to whatever extent). I would say that it is this perceptual equivalence that we call 'accurate' or 'realistic', with the codicil that physical and perceptual equivalence are not directly correlated (in the real world as well as artificial worlds). Incidentally, you can actually uncover that comb filter effect on the cheap, without loads of experimental setup - walk around outside 'till you find an extractor fan, running. Walk toward it, past it, slow down, try small head movements. You can hear quite gross 'EQ' effects and wonder why you didn't before. But be warned - once you hear it, it's hard to unhear... cheers ppl I was Dr Peter Lennox School of Technology, Faculty of Arts, Design and Technology University of Derby, UK e: p.len...@derby.ac.uk t: 01332 593155 ________________________________________ Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound _____________________________________________________________________ The University of Derby has a published policy regarding email and reserves the right to monitor email traffic.
