Title: OT - auditory illusions
Post by: JIPPER on January 18, 2010, 03:17:12 AM
Just read this reply to a post on AA by chrisVH.  http://www.audioasylum.com/audio/cables/messages/14/144268.html (http://www.audioasylum.com/audio/cables/messages/14/144268.html)

The links are the interesting bit here.  They give you a great chance to test your own perception of tone.

I am not trying to discuss copper versus silver cable!

Try for yourself if you have a moment.  not only can the conditions of the test (order of tones) change your conclusion, but in a reference on the information page, subjects from the UK and USA scored differently in repeated trials.  Guess we need to check passports at all future A/B testing!  fun stuff, takes a few minutes to go through it...

Hmmmm... I'm confused by the text.  What does, "Two consecutive tones are always separated by a single semitone," mean?  Does it refer to to tones consisting of two pure pitches?

In listening to the example, that would not close, I heard the first sound as being lower than the second sound.

I think I am not getting something here.

BTW, I think the AA post is extremely well worded.  I'm impressed with the author.

That is Chris Ven Haus -- owner of VH Audio, maker of v-caps, etc.  A good guy for sure.

I was at the Science and Industry museum in Columbus OH and they had a room that was treated to give no echo (anechoic?) and I was floored with how different everything sounded, and wondered how audio would sound there...
