the low tone makes an overtone an octave higher, and by the end of the video the overtone`s pitch has fallen to what the original tone was at the beginning of the video....

Okay.

It starts out with a low note, making you think it went lower, if that makes any sense.

Ugggggh.

It doesn`t work for me.

I see how it`s supposed to, but it can`t fool me.

There was another one that was posted that worked though.

at about 11 seconds it goes back up to a higher octave...

Doesn`t work. And I`m afraid Hansbo, you are tone deaf, because both pitches lower. If you listen though, you`ll notice a pitch an octave higher than the original fades in slowly about halfway there.

It keeps getting lower but it doesn`t really change... I think the ball falling down the stairs etc aids the illusion.

Lame... they play 2 of the same notes, an octive apart. then, when it tells you the sound lowers, your brain only registers the lower note, instead of the higher note already heard...

Lame...

i listened to it like 100 times and almost at the end it jumps back up.

use a recorder and see the difference

Near the end, it goes back up so that when you replay, it sounds lower than that moment, giving that `illusion`...

Yeah, Im a little late on that...

After skipping halfway, I noticed that the octave returns to the beginning?

Did anyone else hear the incredibly high and incredibly low pitched tones?

I think that it is the same note in every octave the ear can hear, yet it falls in pitch steadily to the lower octave. Also, because the mind depicts what we sense, it tells us to hear the lower (and lower, and lower, etc.) pitch, because that`s what we expect, based on our previous experiences and observations.

yeah, its only cuz they`re playing the same notes in 2 octives, and your ear only picks up on the lower one the second time around... yeah, i`m a band geek...

If you start it out and then click towards the last few seconds of the video the tone goes back up.

Weird.

well, i noticed when you hit replay there was a higher pitch overlayed in the deep tone we hear when we hit replay, so we hear the higher tone the first time and the lower one the second time because our minds want it to keep going down, but really, there are two pitches in the same video but out minds only choose to hear one at a time.

yeah, it didn`t work for me either....and i do have musically untrained ears. i keep hearing the ringing high note at the very beginning. i was expecting something really convincing.

Explanation is simple.
More than 1 tone is being played at a time, at the start, you are listening to the higher tone, at the end, you are listening to the lower tone...upon replay, you hear the lower tone, but as it keeps dropping, you keep listening to the lower tone...and so on.

Basically there are two tones, and the lower one jumps up two octaves when it gets to a certain point. This might fool a musically untrained ear, but I didn`t think it was all that convincing.

For this to work, you need to replay it right away. It`s an illusion. The tone that it ends with is there at the beginning, but you start out listing to the higher tone then, the second time through, you are already used to hearing the low tone, so that`s where you start out.

lol

it seems like there`s like a really high note on "top" so that`s the one that has gone down after you replay...
to the lower note that plays at the same time!

haaahahahahahahahaha

quite clever. the video reminds me of that tunnel they go through in Willy Wonka...

Yeah, the main tone is constant. Try making the same tune with your voice, it will stay the same. Or I might be tone deaf.

I think it has to do with the fact that in the beginning there are two similar sounds... One falls, while the other stays constant... Or somewhat like this

The reason you hear the sound going lower is because they play the same note but in different octaves, therefore creating the illusion of the sound getting lower and lower.

yea.. seen this already, but still pretty interesting. im pretty sure the vid plays two sounds at once, an octive (is that how u spell it?) apart, n then both sounds go down a full octive, so wen u replay its like a full cycle. srry, bad explanation, just google it.

very simple concept. If you have a musical ear, the reasoning is quite apparent.
