Speaker 1 (00:00):
Researchers are examining the current landscape of magic tricks, finding
that while visual illusions abound, tricks involving other senses like
touch are rare and focus solely on blah blah blah.

Speaker 2 (00:11):
Here we go.

Speaker 1 (00:14):
Stereo sound manipulates audio timing between our ears to create
the illusion of sound coming from different directions. Movies often
use the shepherd tone, an auditory illusion that gives the
impression of an endless rising pitch to build tension and

(00:35):
keep the audience on edge.

Speaker 2 (00:36):
What is a shepherd tone?

Speaker 3 (00:38):
I don't think I've ever heard that term.

Speaker 1 (00:42):
Says like we've all heard of the Wilheim scream. Yes,
but what is the shepherd tone?

Speaker 4 (00:49):
The brain is tricked into thinking there's a rising or
falling in the pitch.

Speaker 2 (00:57):
What does that mean?

Speaker 4 (00:58):
Always seems like it's setting up or down towards a
particular note, But in reality, it's just an endless loop
of sound that never reaches any destination.

Speaker 2 (01:06):
Oh wait, and that's in movies.

Speaker 4 (01:10):
Wait if we play if we go to YouTube and
play it here, Wait, what is this?

Speaker 5 (01:14):
No?

Speaker 4 (01:14):
But I need this searching shepherd tone? Okay, I don't
really know what to expect her all right, let's try it,
because then I have an idea. But I bet it
makes dogs and cats go crazy.

Speaker 1 (01:24):
All right, let's try this is a shepherd's tone, Diane, Okay,

(01:53):
I get that.

Speaker 6 (02:06):
How long does this go on for the rest of
your life?

Speaker 4 (02:09):
Five minutes?

Speaker 3 (02:10):
Oh?

Speaker 2 (02:10):
Goodbye?

Speaker 4 (02:11):
Wait, so that is not getting continuously higher? It is
just that's no backing us into thinking it is.

Speaker 2 (02:18):
No, that definitely got higher.

Speaker 4 (02:20):
Yes, every definition yours the one I read, And then
what we just heard in the description here illusion is
saying that is it's just the same.

Speaker 2 (02:28):
That sound never changed. Yeah, wrong?

Speaker 7 (02:31):
Did you hear it change?

Speaker 6 (02:32):
Yes?

Speaker 7 (02:33):
Right?

Speaker 2 (02:33):
But is that the trick? Is there anybody we're blind? John?
Did that not change for him? Oh?

Speaker 4 (02:40):
You think he perceives it differently?

Speaker 2 (02:42):
It's like, oh my god, that's like just a droning
tone to make.

Speaker 4 (02:46):
Me uncomfortable because is it using movies? What'd you say
to build suspense? Did you say yes?

Speaker 8 (02:52):
Then?

Speaker 2 (02:52):
And it did?

Speaker 1 (02:52):
I kept waiting for the like the scream or the
yell or whatever, an auditory illusion that gives the impression
of an endless rising pitch to build tension and keep
the audience on edge attention. Said, Wait, so you're telling
me everybody just heard that and it never got higher. Well,

(03:13):
you've played again, because now I'm going to try to
listen to hear it not do anything that it should
just be a drone.

Speaker 4 (03:20):
Do it again, and remember we can ask her after
we play it the second time. Christen's wiring is off
in her head. Oh that's true, so maybe she hears
something totally different.

Speaker 1 (03:29):
Wait, can I ask this? Damn and Tyler? Did you
hear it going up?

Speaker 2 (03:34):
Yes? Like it went trick right, Miley?

Speaker 6 (03:39):
Does it not? Just makes you?

Speaker 2 (03:40):
Is my brain tricking it too? Let me listen again?

Speaker 4 (03:45):
Ready?

Speaker 2 (03:46):
Yeah, what if it goes down?

Speaker 4 (03:48):
This? You know it is so weird and this is
this is how you exposed it. I started it where
we stopped it.

Speaker 2 (03:59):
And it was sounded. Did you really?

Speaker 4 (04:02):
Yeah?

Speaker 2 (04:02):
Wait, so that's weird. Fat you said it's five minutes? Yeah?

Speaker 1 (04:06):
Yeah, go what what what point is it at on
the on the on the video? How many minutes in?

Speaker 4 (04:10):
It's like two minutes?

Speaker 2 (04:11):
Go to the four minute mark?

Speaker 1 (04:14):
Yeah, all right, let me hear how it starts at
the four minute mark or is it a bell curve?

Speaker 2 (04:18):
Is it gonna go down? All right, let's listen don't know.
Here we go, here we go, turn me on. God
damn it, God damn it. It's a bit. It's a bit.
Go to the beginning. Go to the beginning, Go to
the beginning. Drop it anywhere anywhere in there beyond there go.

Speaker 4 (04:40):
Oh no, that sounds different.

Speaker 2 (04:41):
It sounds higher. It sounds higher.

Speaker 6 (04:44):
But is it because we're not?

Speaker 4 (04:45):
If we if we take a pause from it all
two or three, flush it out of our system.

Speaker 2 (04:50):
Flush ship out your sists, dumb hit it. Nope, it
picked up higher?

Speaker 4 (04:57):
Can someone explain this to us?

Speaker 2 (05:00):
So you guys aren't here in just one tone, straight
through the whole way.

Speaker 6 (05:03):
I am Kristen.

Speaker 2 (05:05):
Is that legit?

Speaker 4 (05:06):
Do you understand what this is? You went to school
for stuff?

Speaker 2 (05:09):
You have an answer, Christian? Can you turn yourself off sale?

Speaker 4 (05:12):
Did you guys discuss this with engineering and mixing? Not really,
because I didn't take that.

Speaker 2 (05:25):
That's like George. Did they discuss the classics? Not really?
I didn't take it.

Speaker 1 (05:30):
I don't know, I didn't take it. Wait, so I'm
I hate to be obsessed with this.

Speaker 2 (05:39):
Now I need I need? What do I need? I need?

Speaker 4 (05:42):
Like?

Speaker 2 (05:42):
Who lives in that world of like audio engineering?

Speaker 3 (05:45):
You know?

Speaker 2 (05:45):
Who I need right now? JJ Abrams, God damn it, Grace,
he get off the phone. He could explain it.

Speaker 1 (05:50):
No, no, but with somebody who works like in the
theater department at not the theater department, like the film.

Speaker 6 (05:55):
School or something like sound design, Yeah.

Speaker 1 (05:59):
Sound design, or somebody who's in film at school and
does like all the sound and stuff.

Speaker 4 (06:05):
Or who is that ear?

Speaker 2 (06:05):
Doctor?

Speaker 6 (06:07):
Are the one who made Jones?

Speaker 2 (06:09):
What's her name? Is it a lady? Yeah?

Speaker 6 (06:12):
I believe so.

Speaker 1 (06:13):
Yeah, Well why would she know? She makes she makes
it so you can't hear what? No, she helps you
hear the is that one tone? Is there somebody listening
who only hears that is one?

Speaker 2 (06:26):
Even drone?

Speaker 4 (06:28):
No, there were definitely multiple sound ways to you, to
all of us.

Speaker 1 (06:34):
Yes, but by the way, anybody watching a movie would
say the same thing.

Speaker 4 (06:38):
But explain the illusion. That's what we want, explanation for
what's happening there.

Speaker 1 (06:41):
Yeah, we remember once you hear the Are you asking
me a question? Yes, yes, go ahead.

Speaker 4 (06:46):
Have you thought about listening to it again?

Speaker 6 (06:48):
But with your eyes shut?

Speaker 2 (06:50):
That's a great question. No, that's a great that's a
great Are.

Speaker 4 (06:53):
You asking that of Elliot or John?

Speaker 6 (06:55):
You think that'll make a difference.

Speaker 2 (06:56):
John doesn't have to close his eyes.

Speaker 4 (06:58):
Okay, all right, So is this gonna be eyes open,
her eyes closed?

Speaker 2 (07:02):
Well, I've already done it twice with my eyes open. Okay,
it just relaxed. Why are you covering your face?

Speaker 6 (07:07):
Can't your eyes?

Speaker 4 (07:08):
Close your eyes? I don't want your hands.

Speaker 1 (07:09):
No. I don't like to close my eyes because it
makes it blurry. But if you just cover your eyes,
then it's.

Speaker 6 (07:13):
Oh you're not even closing your eyes.

Speaker 2 (07:15):
Why do I have to? It's pitch black?

Speaker 4 (07:16):
You have to close them?

Speaker 6 (07:18):
Oh, je in the moment.

Speaker 2 (07:19):
You never took the class, Christian.

Speaker 4 (07:21):
I'm just trying to pretend I'm blind, which she does
a few times a week.

Speaker 2 (07:36):
All right, here I go. My eyes are closed. I'm
pretending I'm.

Speaker 4 (07:40):
Blind, like when Elliott moons us pretend we're blind.

Speaker 2 (07:44):
Here we go. All right, I'm still hearing it go up.
I don't want to speak for everybody.

Speaker 6 (07:54):
Same, same what It's the same as when my eyes
were open.

Speaker 2 (07:57):
Oh okay, I thought you meant it's the same tone.
How does nobody hear that going up?

Speaker 3 (08:02):
Relax?

Speaker 5 (08:03):
Elliott?

Speaker 2 (08:04):
I did it. I could not be more relaxed.

Speaker 4 (08:07):
Misinterpreting it. We hear it as continuously rising, but it
never really does.

Speaker 2 (08:15):
Yeah, that's the definition. Yes, but it's it is going up.

Speaker 4 (08:19):
But we're here. Yes, but everyone is hearing it. I
think ascend, but but it's not.

Speaker 2 (08:26):
It is it is. But here's what I'm saying.

Speaker 1 (08:30):
If you're a magician, if I'm a magician, right, yes,
I'm piff right and shim Limb is in the crowd,
and I do a magic trick. Everybody watching may know
what it is, but shim Limb knows what it is
because he's a magician. There's somebody out there who's like,
it's not changing. Do you understand what I'm saying. Yeah,

(08:50):
so all of us dummies, we're here. We still haven't
heard back from Blind John. Maybe he dropped the phone,
can't find it. But that's sound changes.

Speaker 2 (09:03):
ALTYO.

Speaker 1 (09:05):
Well you know I used the uh, I used the
shepherd's toad on dope sick.

Speaker 4 (09:13):
He writes, I've always called them risers. Oh, I use
them all the time in video editing. Oh Jesus Christ,
But he doesn't explain it.

Speaker 1 (09:21):
I took a picture of King Hoon John, it was
actually kinghon Elliott.

Speaker 2 (09:31):
I just I don't get it. I don't get it.
Chris chiming back and he is he blind?

Speaker 7 (09:36):
No?

Speaker 4 (09:37):
He had us look at the blind magician or oh yeah,
yeah yeah. The trick to the audio tone is it
appears to be constantly rising in pitch, but it really
is is multiple sounds on a loop and never reaches
anything higher, even though it sounds like it's constantly rising. Wow,
I don't even understand what he just typed Billy the

(10:00):
Capitol Carrier checking in, Oh, here we go. He is
hearing the sound change as well. Excellent, thank you, Thank you.
Also worth pointing out not blind.

Speaker 6 (10:10):
No, that's up.

Speaker 4 (10:13):
What he wants to know? Who's left? It sounds like
a ship is pulling us out of the studio each
time we play it, like is Kristen gone?

Speaker 3 (10:23):
Now?

Speaker 8 (10:25):
Hi?

Speaker 2 (10:25):
Elliott in the morning? Yeah, Hi, who's a.

Speaker 5 (10:33):
Pat from Melviwsburg.

Speaker 2 (10:35):
Yes, you're gonna explain the shepherd tone to me.

Speaker 5 (10:39):
I'm not gonna explain to Tom, but I'm gonna explain the.

Speaker 2 (10:41):
Illusion here it goes.

Speaker 1 (10:42):
Go ahead, Oh, the illusion is it sounds like it's
getting higher, but it's not.

Speaker 2 (10:48):
You already know what he's gonna say. He's gonna no, no,
call me stupid.

Speaker 5 (10:52):
No, no, no, I'm not believing you. The illusion is
that it's a loop.

Speaker 7 (10:56):
It keeps getting it.

Speaker 5 (10:57):
Keeps restarting like a round, like and like if you're saying, uh, Michael,
row your boat ashore or ro row your boat, and
you're starting around, it keeps looping. It's never ending.

Speaker 2 (11:11):
Yeah, but okay, I understand what you're saying.

Speaker 1 (11:13):
So so what you're telling me is it's the second
hand on a clock, and eventually the second hand gets
back up to twelve and it starts over again.

Speaker 5 (11:25):
No, it's it's if you had two second hands going
in the same direction but an opposite.

Speaker 7 (11:30):
End a spectrum.

Speaker 3 (11:32):
So one would start at twelve and one would start
at six, and they would move in the same direction.

Speaker 2 (11:39):
Then how does it start over?

Speaker 6 (11:40):
I can't believe I got that.

Speaker 2 (11:45):
By the way, you can't ex Diane. I'm just I'm
the ranking Diane.

Speaker 4 (11:51):
That's the second dumbest thing that's been said during this break.

Speaker 2 (11:54):
Did Chris to get the first one? Oh?

Speaker 1 (11:56):
Yeah, but that doesn't make any.

Speaker 5 (12:03):
The pitch gets so high eventually that you can't hear
it snap out, And right as that snaps out, you
can't hear that the tone at the bottom end of
the spectrum starts in, so again it sounds like a
looping forever loop?

Speaker 2 (12:17):
Am I am?

Speaker 6 (12:20):
Like a dog whistle?

Speaker 2 (12:22):
No dog whistle? Is just the pitch is so high
you can't hear it? Or is it bad jeans? Probably?
All right? All right, all right, thanks for clearing that up.

Speaker 4 (12:36):
Okay, how about Diana got the two hands?

Speaker 6 (12:40):
Though heast tiers stood that part?

Speaker 2 (12:42):
How about the rest of it? Now? Can I be honest?
I feel stupid?

Speaker 4 (12:49):
Green says. The illusion is that it is continuously rising,
not that it isn't rising at all.

Speaker 1 (12:56):
Wrong because we heard it when we started again where
it sounded lower, which goes back to what that guy said,
it's a loop.

Speaker 4 (13:04):
Some people are claiming they can hear the higher and
lower notes either fade in.

Speaker 2 (13:08):
Or fade out. No they can't.

Speaker 1 (13:11):
I got headphones on. I got studio headphones on. I
mean they're loud because you are deaf.

Speaker 2 (13:16):
Yes, that you are.

Speaker 6 (13:18):
I know you get those two mixed up.

Speaker 4 (13:21):
Kristen occasionally is blind by choice.

Speaker 2 (13:27):
Where am I going? Line three?

Speaker 5 (13:30):
Hi?

Speaker 2 (13:30):
Elliott the morning?

Speaker 3 (13:32):
Hey?

Speaker 8 (13:33):
Have you ever seen the barber pole in front of
a hair salon? The rotating candy cane looking thing. Yeah, sure,
this is effectively that with sound. It looks like it's
traveling upward. But it's just a repeating cycle. Okay, that
makes sense.

Speaker 2 (13:50):
Yes it does. But here's the difference.

Speaker 1 (13:53):
Right, I understand, I understand what you're trying to say,
and I understand that the illusion is that it's curling up, right,
But but we know it's not. It's and you can
and you can know that, right, you can know that
I'm hearing this get higher pitched.

Speaker 8 (14:15):
But the trick in your brain, though, is your ears
are not seeing where one tone ends and the next begins,
where it loops around.

Speaker 2 (14:23):
Don't need to because I hear it.

Speaker 8 (14:26):
I know that, But your brain is actually tricking you.
It's not interpreting it the way that it actually is.

Speaker 2 (14:34):
So it's not really getting higher pitched.

Speaker 8 (14:37):
No, it's just a cycle of the same sound, many
many different sounds, overlaid like each of the red lines
on the barber pole. Right, it's multiples of those. Let
me ask offset by a fraction.

Speaker 2 (14:51):
Let me ask you this.

Speaker 1 (14:52):
When we played it, did it sound like it was
getting higher pitched to you?

Speaker 2 (14:57):
Okay? Good?

Speaker 4 (14:59):
What's the origin story of the barber pole?

Speaker 1 (15:03):
It's uh, you know, it's the somebody was like, we
need a shepherd's tone.

Speaker 2 (15:07):
But for visualization, it just catches your eye.

Speaker 4 (15:14):
It's got to be a better story than that.

Speaker 2 (15:17):
All right, very good, very good, Thank you? What Diane.

Speaker 3 (15:21):
The barber pole originated in the European Middle Ages as
a way to symbolize the dual roles of barbers as
both hairdressers and surgeons. It has some sort of blood
letting imagery to it.

Speaker 2 (15:34):
Wow, can we study the stripper pole instead?

Speaker 7 (15:37):
Oh?

Speaker 2 (15:37):
Wait, line three? No, no, no, line three. Hi, elliot in.

Speaker 7 (15:41):
The morning, mister Siegel, I should start charging you an
hourly rate. I'm joking.

Speaker 6 (15:46):
I'm joking.

Speaker 1 (15:47):
By the way, this is blind John, Hey, John, Yes, yes, sir,
it is. Are you Are you hearing that sound get
higher pitched?

Speaker 2 (15:57):
Yes?

Speaker 1 (15:58):
You missed a prime opportunity to lie, my friend, so
you're hearing it?

Speaker 2 (16:02):
Also?

Speaker 4 (16:06):
Yeah, did it feel I don't know.

Speaker 1 (16:09):
I only know it from a sighted person's standpoint, So
you don't feel like I just did a magic trick
to you.

Speaker 2 (16:19):
No, well, back to the drawing board. Yeah, okay, all right,
very good?

Speaker 8 (16:26):
Really not right?

Speaker 7 (16:27):
Oh no, no, wait, wait, Ellie, hold on, wait, I'm worried
if my ears are messed up, I got real problems,
like another strike.

Speaker 1 (16:37):
No, so everybody hears it like that, but it's just
an illusion.

Speaker 2 (16:41):
Wait, what are you pulling up now?

Speaker 4 (16:43):
Nothing? I was gonna if you needed to hear it again.
Or was it Ryan who said he's high? Sounds great?

Speaker 1 (16:51):
Okay, somebody else says they can explain it to us.
I'm just gonna try one more. It's not Joan the moone.

Speaker 6 (16:57):
Is it like Hoby No?

Speaker 1 (17:00):
Honestly, hey, y'allre It's like when you spit hi Elliet
the morning.

Speaker 7 (17:08):
Hey, this is me, Yes, hey, uh, this is Matt Stronom,
doctor Amber's husband.

Speaker 2 (17:16):
Okay, she built a telescope for NASA. What do you got?

Speaker 7 (17:20):
Yeah, well yeah, not NSA. Uh, definitely not natal affiliated.
So the last color kind of had it right. So
Tyler pull up a like a visual of the shepherd's
tone and that will explain it. So it is absolutely rising.
It's like a series of four or five tones that
individually rise kind of one after the other. So it

(17:43):
sounds like it's going up, and it is going up.
You're hearing that, right, but it just repeats and recycles.

Speaker 2 (17:51):
If it were on the barber pole, it would.

Speaker 1 (17:53):
Go wing wing wing wing.

Speaker 7 (18:00):
Right, But so like the red is turning up and
going up, and then the white is coming right behind it,
and then there are another one's coming up right behind it.
That's what you're hearing.

Speaker 1 (18:08):
No, I'm hearing, but I'm hearing one continue.

Speaker 7 (18:11):
But it only goes up. That's the illusion, right, it
only goes up so high. And then that's why, like
when you restarted the sound, like in the middle, it's
kind of kind of low, and it continues to build.
So if you look like at a visual of the
shepherd's home, you will see the different tones as they
kind of go up because they fade out as well.
So it will. I don't hear that louder, and then

(18:33):
it gets higher, it fades out.

Speaker 2 (18:36):
Here's my problem, right, here's my problem. As I'm listening
to it. Thank you, doctor Aber's husband, I'm not hearing
it start up again. Now are you hearing it start
up again?

Speaker 4 (18:52):
No?

Speaker 2 (18:53):
Give me a seconds, m Maybe the answer is out
