The Infinite Sound That Can Drive You Insane-Shepard Tones

In this video I show you a sound that seems to continually rise in pitch but never actually does. I show you how to make a Shepard tone, and how they work.

I have been going to counseling for mild anxiety, and was recently discharged. I can confirm, the sound and video combination did cause mild anxiety. To satisfy anyone's curiosity, it was a similar feeling to freefalling on a roller coaster, but more discomforting, and my breath did shorten. Personally, it was mild enough that I could handle the full audio. I do not recommend for anyone that suffers from anxiety or panic attacks. But, if you must, try only the last few seconds starting at 1:36. (I'm absolutely completely fine. very mild, very interesting)

[@Games_and_Music]

Yeah, i had a hard time getting fooled by this, as i pretty much immediately spotted the flaw in this infinity, it's just a loop of shifting octaves, or as we learned on elementary school to sing in canon, which sounded the same in certain songs, if they had the repeating octaves of course. But yeah, this was nothing new to me, other than i never knew it had a name to it. I had the same with the whole "Laurel / Yanny" thing, i heard both at the same time and could switch between hearing one or the other. EDIT: besides it just sounded like a typical pop song build up to a beat drop, that's also why it gives that physical/mental feeling of anxiousness, because it's designed to get you going.
