The Tritone Paradox

[bigjohn]

I hear : up, down, up, down

all a bit mad like. Does sound like the Simpsons though.

[SteveK]

Had another listen on PC speakers (slightly better quality than my laptop )
And, guess what? I still think the first two ascending and last two descending...sounds so obvious.
But as no one else is hearing it, I am preparing my face for the egg that is obviously going to be heading my way

[ThomBassmonkey]

up down up up, hum along with them

[Wil]

On headphones it was all ascending, now on my laptop it's 2 down, 2 up. Odd.

[51m0n]

1,2,3 up, 4 down for me (on decent Sennheisers)

Fascinating......

[charic]

The one that will really mess with your head if you like psycho-acoustics is Shepard-tones. Now they're messed up!

There's one that continuously seems to get faster and faster that works on the same principle

Think we've all played with drummers that work on a similar principle.

Hmmmm, it doesnt get lower so much, in that the fundamental definitely stays the same, but it does get higher as it pops back up to the top of the sweep.

Thats cool! Some very groovy/trippy/weird effects to be had with that. Can you reverse it so it always rises?

The other one doesnt speed up for me, errrr what does that mean??

I meant to put that there is one that seems to get consistently faster but I can't remember its name. It was all part of Acoustics and PsychoAcoustics (my favourite module).

[jackers]

also, that bang goes the theory vid is good simon thanks for posting it.

[derrenleepoole]

Man that's bloody weird! I got descending, ascending, ascending, descending.... and then I listened again and again and again... and simply couldn't decide.

I've now posted this to FB and all my muso friends so they can have a headache too

[FuNkShUi]

I got ascending, ascending, descending, ascending
Its definitely trippy, think we can all agree on that

[xilddx]

I get D D D A

It's basically exactly the same thing- different octaves of the same note, the dominant one being the one you hear. I'm not sure it is so much an audio "impossible staircase", more like trying to climb a set of stairs but someone keeps building new storeys faster than you can walk up them...

[quote name='Count Bassy' timestamp='1340665122' post='1707959']
To me it's down down up up, quite clearly, but others obviously differ. But surely whatever 'flat response' equipment you listen to it on your ears are far from a flat response and will vary with age and the amount of abuse they've had etc. On top of that is how you listen to things. As bass players perhaps we tend to listen to the lower harmonics rather than the higher ones.

I'v always thought that part of the reason some people like a particular piece of music and others don't is that, internally, they are hearing different things.

I think that is exactly the point of this test; because it is augmented 4ths, your perception of whether it goes up or down or not depends on what range sounds dominant to you. For example, you might hear the middle of the 3 octaves for the first note but when it goes down, that middle one might go out of your range and you will hear the upper one instead, tricking you into thinking it is ascending when it actually descends. That's how all of these things work. They say a flat frequency response because they want to isolate the effect your hearing perception has on what you hear.

First time round I couldn't really tell, but listening to it again it seemed like the only sound I could hear was the fundamental note. Anyways 1 2 3 up, 4th down

On bad laptop speakers

[Booooooom]

listened twice through desktop computer speakers, definitely in my mind its decending decending accending accending...

could explain why when trying to work out a song it can sometimes be a struggle finding the next note.

I agree, tried whistling along and I'm even more sure.

[Protium]

Up, up, up, down

[phil.i.stein]

try this with ONE speaker, and ONE ear, the stereo 'illusion' makes a difference !

report back later.

[phil.i.stein]

on headphone, one ear i still get 1&2 descending, 3&4 ascending.

freaky how people hear things differently (or maybe not)
