Ralf11 Posted October 5, 2018 Share Posted October 5, 2018 so Jana Dagdagan turned down the old lasagna job and went straight to YouTube? Good for her! very Millennial... Link to comment
Ralf11 Posted October 6, 2018 Share Posted October 6, 2018 Using a dummy head is exactly what scientists and engineers do to design equipment or study audition. However this particular dummy head is very squared off, so may only be applicable in Scandihoovian countries... Link to comment

Time and intensity differences as well as pinna filtering and head movement. The brain appears to peg a location for initial direct sound, and as long as the various directional cues agree it blocks out delayed reflections. As each of the known directional cues are removed, the accuracy of our perception of location is reduced. I don't know that I can point to research showing directional cues from pinna specifically are used for filtering of reflections, but as pinna directionality is one of the factors in our hearing of location(especially height) it seems it will be involved. ... also phase detection there is an extensive literature on this topic - here's a starter: https://acousticstoday.org/wp-content/uploads/2016/01/The-Evolution-of-Mammalian-Sound-Localization.pdf Link to comment
Ralf11 Posted October 9, 2018 Share Posted October 9, 2018 Hey Frank - do you like MQA? Link to comment
Ralf11 Posted October 11, 2018 Share Posted October 11, 2018 maybe the goal to get much of an idea of how it sounded is not possible, but perhaps some correlates of various sound quality factors between 2 different systems could be compared? Link to comment
Ralf11 Posted October 11, 2018 Share Posted October 11, 2018 that's the typical way, sure but various labs have used dummy heads with mics for various things - I dunno what has been done with relevance to human audiophile factors off the top of my head tho... Link to comment
Ralf11 Posted October 11, 2018 Share Posted October 11, 2018 Frank, I have a dummy head you can tune... Link to comment
Ralf11 Posted October 12, 2018 Share Posted October 12, 2018 One of you might want to let Jana Dagdagan know about this. I don't know if she has any technical background or not (just that she is nice, female and young - so different from most audiophiles...) Link to comment

So that would mean soldering all the connections between neurons. Which will take some time. Frank speaks about it taking lots of time. It also means the normal plasticity of the brain to re-wire its connections would be impacted. Which might lead to repeating the same thing over and over and over until you didn't realize there was anything else. Great idea!! Think of the increased speed when you eliminate the slow diffusion of neuro-transmitters esldude 1 Link to comment
