How can we hear the difference in cables in a bad room?


Hi after spending the last months measuring my room with REW and reading about room acoustic in small rooms.
I began to wonder how we can hear differences in equipment when the frequency respons in most rooms are bad.

Just think about it! a power cable - why can you hear a difference? is it a timing issue, noise? are the human hearing much more sensitiv to delay / phase issues than frequencies.

If you have knowledge in this area then I would love to be educated (:

Happy new year to all of you.

audiozenology,

Thanks, I completely forgot about saccades as a term.

Given the magnitude of the flickering light presence everywhere, it is interesting that not many articles about its effects can be easily obtained on PubMed. It may be that more of that research is funded by the industries rather than by the traditional bio-science so it ends elsewhere.

If I understood this abstract correctly, my semi-wild guess about "being fooled" is semi-correct. Makes me semi-proud.

At the same time, to stay in the audio realm, this one connects saccadic eye movements, fooling, and auditory stimulus in one neat mix.

This was good as it made me look it up. Quick PubMed search produces mostly articles about accomodation response to flickering (and comparisons of different frequencies at that). I could not find anything about extraocular muscle involvment, though. The articles I skimmed are a bit old and had only abstracts without the section method.

Is there some explanation of the mechanism for this extraocular muscle involvement with flickering? Maybe repositioning after being fooled that the object moved slightly?

Not much to do with audio reproduction, but interesting to think about, anyway.
"...placing extra burden on image processing, and on the extraocular muscles..."
Assuming that flickering light is the only "abnormal" condition during this reading, is it extraocular or intraocular in this case?
