this is real and for once
truth is scarier than fiction

hello Internet welcome to game theory
the show that either ruins her childhood
or makes you fear for your life
sometimes we do both at the same time
and those episodes are the special ones
sure sometimes we cover fun things like
quantum physics or poop jokes but lately
the show's been in a bit of a blue
period blame it on the winter I suppose
but we've gone to some pretty dark
places recently nearly sentient killer
robots at the rods from outer space
cataclysmic planetary events you know
the usual stuff par for the course
falling in line with that pattern today
we're talking about sound a topic which
at first seems harmless enough you know
it's pretty important to what we do
every day it's also the thing that's
allowing you to listen to me right now
but it can also be dangerous dangerous
enough to be a weapon dangerous enough
to do some real damage dangerous enough
to blow your skull apart so crank those
speakers up to 11 as we prepare to talk
about a killer that's both silent and
deadly and not a fart so way way back in
May of 2011 the fourth episode of the
series was dedicated to the real-life
equivalents of Mortal Kombat fatalities
pretty intense stuff being frozen to
death having your heart ripped out
getting poisoned by reptiles kisses and
kisses from reptiles but there was one
fatality that I really wanted to cover
that I just didn't have time for and
that was smoke blowing up the planet
using chest bombs which I did seven
episodes later but there was another
fatality that I just wanted to okay it
was Sindel blowing up a head with the
power of sound is that possible you know
I'm not gonna beat around the bush here
it is and not only is it
it can happen to you at practically any
moment without you realizing what's
going on but in order to understand that
scary little thought we have to review
the basics of sound first so let's start
at square one what is sound how can
something invisible possibly cause
someone's head to pop like a 16 year
olds imple well sound is a bunch of
pressure waves vibrations that travel
through air water or something else I
snap my fingers and I cause the air
around my hand to vibrate like ripples
in a pond with those ripples eventually
reaching my ear allowing me to hear the
sound of the snap that's why in the
vacuum of space no one can hear you
scream
literally there is nothing there to
vibrate in thus carry a scream sound or
gunshot sound ghost Cod hear me I'm
looking at you oh for as cool as these
scenes are Isaac Newton just facepalm
doll over this game since sound is a
pressure wave it most often gets
represented like this now there are four
different numbers that you can use to
describe a sound wave wave Lang period
amplitude and frequency but the one
that's going to help us the most in
popping a head right now is frequency
which measures how many vibrations or
ripples there are per second say I pluck
a string pluck it good and hard but only
after treating it well and showing it a
good time first if my pluck starts in
this position the number of times the
string reaches that position again in a
second can be said to be its frequency
this speed and turn affects the pitch of
the sound more vibrations per second
produces a higher pitch and fewer means
a long one this number of cycle per
second is measured in hertz hurts like
the rental car or the donut Hertz donut
now as anyone who's ever used a dog
whistle knows the human ear can't hear
all frequencies of sound the sound
that's leaving the whistle and driving
the dog crazy sounds like nothing to you
the frequency is too high for the human
ear to process but there are also sounds
that are too low for human hearing in
general you can hear frequencies between
20 Hertz and 20 kilohertz anything with
a frequency below that low 20 Hertz
threshold is called infrasound and
though we might not be able to hear it
it can certainly affect us in some
pretty bizarre and disturbing ways now I
have to ask do you trust me because I'm
about to play you a very brief example
of infrasound now don't worry you'll be
fine or at least you should be here it
is did you hear that or rather did you
feel that some of you probably didn't
and that's because many headphones and
speakers can't produce that low of Hertz
it's called frequency response the range
of possible frequencies a set of
speakers or headphones can produce so my
apologies Cod fan 27 365 your
turtlebeach air force X 12s ain't gonna
cut it to demonstrate how bizarre this
is for me my headphones can produce the
sound but my speakers can't that said
for those of you who could hear it it
probably didn't sound like all that much
but chances are you probably also felt
it the low frequency of infrasonic sound
means it has a longer wavelength which
makes it easier to penetrate your body
and shake things up the weird part about
this is almost any part of your body
based on its volume and makeup will
vibrate at specific frequencies this is
what's known as its resonant frequency
the tone at which an object or in this
case body part vibrates the most take
for instance your eye it's been
documented that when placed in a room
with a fan resonating at around 19 Hertz
almost the exact resonant frequency of
the human eye test subjects start to see
ghostly gray shapes floating in front of
them when the fans removed the shapes
disappear or another example at Brown
University there used to be the elevator
to hell a seemingly innocent elevator
with a bent fan that produced
undetectable infrasound going as little
as two floors ended up with the rider
feeling nauseous all of this forms the
basis of what's known as vibro acoustic
syndrome the effect of infrasonic output
not on your hearing but on the various
fluid-filled parts of your body and you
know what else is a fluid-filled part of
the body the head all objects have
limits to how much they can stretch when
subjected to
so if you find the right frequency and
then put enough power behind that
vibration they'll stretch and stretch
until they can't stretch no more
resulting in well fatality for sound
this comes down to a matter of decibels
the measure of a sounds loudness for
example a quiet garden about 30 decibels
a chainsaw 1/10 iPod and max volume 115
your cry of anguish when you were on the
last boss and he was like one year away
and he hits you with that unfair attack
you just can't dodge damn it's 165
decibels actually that's not true that's
more along the lines of firing a shotgun
next to your ear but still it feels that
way anything above 125 is going to cause
you pain and potential hearing loss but
because of the frequency of all of these
sounds we know that they're loud and
that they hurt and that we should
probably avoid them the scary thing
about infrasound though is that since we
don't hear these frequencies very well
we're often unaware of exactly how loud
they are let me spell that out for you
you could be hearing destructive levels
of infrasound without actually hearing
it all this high-pitched screeching
Sindel is doing totally unnecessary what
you would be feeling is just this
bizarre pressure coming from somewhere
you wouldn't even know specifically this
is what you would experience at 130
decibels the inner ear would start
undergoing distortions that will affect
your ability to understand speech at
about 150 decibels you're gonna start
complaining about nausea and whole body
vibrations by the time you're at 166
you'll start noticing problems breathing
as the low frequency pulses start
impacting your lungs reaching a critical
point at about 177 DB when infrasound
from 0.5 to 8 Hertz can actually force
you to breathe against your will that's
right sound would literally be
controlling your body at that point so
really we could kill you simply by
stopping your breathing with the
equivalent of a prolong the silent
shotgun blast but if we really wanted to
be a showboat about it and pop your head
like a firework or
that scene from scanners we'd have to
crank the DB's up to something
substantial around 240 since the head is
so well insulated and that sounds like a
lot it is absolutely
but as loyal theorists know this is the
part of the show that gets you to
question your decision to leave your
house every day so it must not be that
much to which I say behold
LRAD the long range acoustic device able
to focus sound into a concentrated beam
and project it loud and clear for over
two miles to miles that's more than I
can run ever this thing is like a sound
launcher so powerful one of its key
selling features is being able to equip
it into a helicopter shoot it at the
ground and still make people cringe -
hams in the boom Bob and that's no joke
you literally can hook up your iPod and
blast anything you want out of it and
that includes infrasonic tones add that
to this fact bullhorns operate at 90
decibels this guy can reach 160 -
without breaking a sweat let me remind
you that number is well over the limit
of causing prolonged hearing damage and
only for shy of causing those breathing
problems I mentioned earlier turn off
this safety switch on the back here and
who knows how powerful this thing can
become I actually couldn't find any
documentation that says this bad boys
been used against protesters and pirates
uh not that type of pirates yeah that's
more like it
captain Phillips would have been a much
shorter movie with some LRAD but in all
seriousness this thing can save lives
deterring enemies without needing to
fire a bullet in fact it's been used as
an effective defense mechanism against
enemy soldiers which is great but then
you have it being used against peaceful
protesters trying to exercise their
rights to free speech not so good and if
it really got into the wrong hands well
you'd have yourself a silent helicopter
mounted head burster with unlimited ammo
just waiting for someone to crank up the
volume so yes sandeul's fatality here is
not only possible but a real thing a
real scary thing a silent long distance
much scarier than a dead-eyed Bride of
Frankenstein ripoff so thanks for
listening
at least this time you had a choice but
hey that's just a theory a game theory
thanks for watching welcome back to the
super amazing card tournament where last
time you overwhelmingly said no.2 C OD
today we're playing a game of would you
rather with some of my favorite Mortal
Kombat fatalities so would you rather
get your leg ripped off and then beaten
to death with it or get punched where
the Sun don't shine only to have your
bottom half explode and your top half
fall to the ground they're both so
appealing click on one to choose but
before you do make sure you give a good
old ball punch Johnny Cage style to the
subscribe button so that's about it
maybe next time we'll do something
happier that doesn't involve death
that'd be great
I'd like that maybe I'll do that you'll
just have to tune in and see
