Can Sound Exist In a Vacuum Chamber?

hey guys I’m Nate welcome back to a

hey guys I’m Nate welcome back to a workshop today we’ve got a fun

workshop today we’ve got a fun

workshop today we’ve got a fun experiment where we’re going to see what

experiment where we’re going to see what

experiment where we’re going to see what happens if we put a microphone and a

happens if we put a microphone and a

happens if we put a microphone and a speaker in our vacuum chamber as many of

speaker in our vacuum chamber as many of

speaker in our vacuum chamber as many of you probably know sound waves are

you probably know sound waves are

you probably know sound waves are vibrations in the air around us and so

vibrations in the air around us and so

vibrations in the air around us and so in theory if we take away that air those

in theory if we take away that air those

in theory if we take away that air those sound waves should no longer propagate

sound waves should no longer propagate

sound waves should no longer propagate and we shouldn’t be able to hear

and we shouldn’t be able to hear

and we shouldn’t be able to hear anything we want to try putting that to

anything we want to try putting that to

anything we want to try putting that to the test in a few different ways as a

the test in a few different ways as a

the test in a few different ways as a first test let’s try putting our speaker

first test let’s try putting our speaker

first test let’s try putting our speaker into the chamber but leaving all of the

into the chamber but leaving all of the

into the chamber but leaving all of the air in and see how much of the sound our

air in and see how much of the sound our

air in and see how much of the sound our microphone can pick up right outside the

microphone can pick up right outside the

microphone can pick up right outside the glass wow that’s a huge difference right

glass wow that’s a huge difference right

glass wow that’s a huge difference right there well I guess we know that glass

there well I guess we know that glass

there well I guess we know that glass and thick Plexiglas does a good job of

and thick Plexiglas does a good job of

and thick Plexiglas does a good job of dampening sound all on its own all right

dampening sound all on its own all right

dampening sound all on its own all right I think we’ve pretty well established

I think we’ve pretty well established

I think we’ve pretty well established what its gonna sound like with our

what its gonna sound like with our

what its gonna sound like with our speaker in air inside the vacuum chamber

speaker in air inside the vacuum chamber

speaker in air inside the vacuum chamber so now we need to try pulling out the

so now we need to try pulling out the

so now we need to try pulling out the air but I also want to make sure that we

air but I also want to make sure that we

air but I also want to make sure that we aren’t just blasting too much sound

aren’t just blasting too much sound

aren’t just blasting too much sound straight into the glass because that can

straight into the glass because that can

straight into the glass because that can also conduct the noise so to add a

also conduct the noise so to add a

also conduct the noise so to add a little bit of padding let’s throw some

little bit of padding let’s throw some

little bit of padding let’s throw some cotton balls down into the bottom of our

cotton balls down into the bottom of our

cotton balls down into the bottom of our chamber and make sure that our speaker

chamber and make sure that our speaker

chamber and make sure that our speaker is facing the correct direction this

is facing the correct direction this

is facing the correct direction this speaker actually blasts the sound out of

speaker actually blasts the sound out of

speaker actually blasts the sound out of the back

the back

the back so we’ll try putting it face down on top

so we’ll try putting it face down on top

so we’ll try putting it face down on top of a pile of cotton balls to make sure

of a pile of cotton balls to make sure

of a pile of cotton balls to make sure that we’re really playing into a vacuum

that we’re really playing into a vacuum

that we’re really playing into a vacuum as much as possible that seems like a

as much as possible that seems like a

as much as possible that seems like a good amount of cotton balls it should

good amount of cotton balls it should

good amount of cotton balls it should keep our speaker off of the glass so the

keep our speaker off of the glass so the

keep our speaker off of the glass so the sound is just projecting into the air or

sound is just projecting into the air or

sound is just projecting into the air or the lack of air once we pull a vacuum

the lack of air once we pull a vacuum

the lack of air once we pull a vacuum now let’s try pulling out a vacuum hope

now let’s try pulling out a vacuum hope

now let’s try pulling out a vacuum hope that our Bluetooth speaker still works

that our Bluetooth speaker still works

that our Bluetooth speaker still works in a vacuum and see if we can hear it

all right air is being pulled out

all right air is being pulled out I admit I hadn’t actually tried seeing

I admit I hadn’t actually tried seeing

I admit I hadn’t actually tried seeing what happens with cotton balls in a

what happens with cotton balls in a

what happens with cotton balls in a vacuum before just now I don’t think

vacuum before just now I don’t think

vacuum before just now I don’t think it’s gonna do anything and it looks like

it’s gonna do anything and it looks like

it’s gonna do anything and it looks like I’m right they aren’t puffing up the way

I’m right they aren’t puffing up the way

I’m right they aren’t puffing up the way marshmallows do because they aren’t

marshmallows do because they aren’t

marshmallows do because they aren’t holding any air

holding any air

holding any air there’s just air in between the fibers

there’s just air in between the fibers

there’s just air in between the fibers this is looking good almost up to a

this is looking good almost up to a

this is looking good almost up to a vacuum we have very little air in there

vacuum we have very little air in there

vacuum we have very little air in there right now at about 25 on this pump the

right now at about 25 on this pump the

right now at about 25 on this pump the most vacuum it pulls is about 26 inches

most vacuum it pulls is about 26 inches

most vacuum it pulls is about 26 inches of mercury all right that is really

of mercury all right that is really

of mercury all right that is really close we’re gonna try calling that good

close we’re gonna try calling that good

close we’re gonna try calling that good let’s see how well we can hear our

let’s see how well we can hear our

let’s see how well we can hear our speaker or not

speaker or not

speaker or not with a vacuum here goes playing the same

with a vacuum here goes playing the same

with a vacuum here goes playing the same clip of music oh if I touch my ear

clip of music oh if I touch my ear

clip of music oh if I touch my ear to it then I can hear a little tiny bit

to it then I can hear a little tiny bit

to it then I can hear a little tiny bit it’s extremely quiet and I can’t hear

it’s extremely quiet and I can’t hear

it’s extremely quiet and I can’t hear anything if it’s on the glass it’s only

anything if it’s on the glass it’s only

anything if it’s on the glass it’s only on the Plexiglas side where the speaker

on the Plexiglas side where the speaker

on the Plexiglas side where the speaker is actually pointed right at it so there

is actually pointed right at it so there

is actually pointed right at it so there may be a tiny tiny bit of air still in

may be a tiny tiny bit of air still in

may be a tiny tiny bit of air still in there or maybe it’s conducting directly

there or maybe it’s conducting directly

there or maybe it’s conducting directly through the speaker into the cotton

through the speaker into the cotton

through the speaker into the cotton balls into the glass through the rubber

balls into the glass through the rubber

balls into the glass through the rubber to the plexiglass I don’t know I’m not

to the plexiglass I don’t know I’m not

to the plexiglass I don’t know I’m not sure how it’s getting there but like

sure how it’s getting there but like

sure how it’s getting there but like this I can barely hear the faintest

this I can barely hear the faintest

this I can barely hear the faintest music other than that see I’m gonna try

music other than that see I’m gonna try

music other than that see I’m gonna try it like pushing it touching this

it like pushing it touching this

it like pushing it touching this microphone to the plexiglass I don’t

microphone to the plexiglass I don’t

microphone to the plexiglass I don’t know if it’ll pick anything up so quiet

know if it’ll pick anything up so quiet

know if it’ll pick anything up so quiet all right let’s let the air back in

all right let’s let the air back in

all right let’s let the air back in while it’s still playing and we’ll see

while it’s still playing and we’ll see

while it’s still playing and we’ll see what happens

letting it in slowly so we can kind of

letting it in slowly so we can kind of see at what point we can hear it

[Music]

[Music] all right that seems like a pretty good

all right that seems like a pretty good

all right that seems like a pretty good conclusive test to me that this does not

conclusive test to me that this does not

conclusive test to me that this does not play well through a vacuum there was

play well through a vacuum there was

play well through a vacuum there was just the tiniest bit of sound that was

just the tiniest bit of sound that was

just the tiniest bit of sound that was able to get through somehow maybe

able to get through somehow maybe

able to get through somehow maybe there’s just a little bit of air in

there’s just a little bit of air in

there’s just a little bit of air in there maybe was conducting through the

there maybe was conducting through the

there maybe was conducting through the other materials inside the chamber but

other materials inside the chamber but

other materials inside the chamber but it was almost completely silent so now

it was almost completely silent so now

it was almost completely silent so now let’s try switching put the microphone

let’s try switching put the microphone

let’s try switching put the microphone inside the speaker outside and see if

inside the speaker outside and see if

inside the speaker outside and see if the microphone can pick anything up all

the microphone can pick anything up all

the microphone can pick anything up all right let’s pull all the air out and

right let’s pull all the air out and

right let’s pull all the air out and then we’ll turn on the sound and see if

then we’ll turn on the sound and see if

then we’ll turn on the sound and see if the microphone can pick anything up all

the microphone can pick anything up all

the microphone can pick anything up all right let’s call that good microphone is

right let’s call that good microphone is

right let’s call that good microphone is still recording we’ll see if it can pick

still recording we’ll see if it can pick

still recording we’ll see if it can pick up any of the sound here goes

all right now also as an experiment

all right now also as an experiment let’s try touching the speaker to the

let’s try touching the speaker to the

let’s try touching the speaker to the glass and the plexiglass and see if it

glass and the plexiglass and see if it

glass and the plexiglass and see if it picks anything up like that all right

picks anything up like that all right

picks anything up like that all right let’s let the pressure back in and we’ll

let’s let the pressure back in and we’ll

let’s let the pressure back in and we’ll find out how it went

find out how it went

find out how it went I’ll try letting some music play while

I’ll try letting some music play while

I’ll try letting some music play while it depressurizes to see at what point

it depressurizes to see at what point

it depressurizes to see at what point the microphone starts picking things

the microphone starts picking things

the microphone starts picking things back up

back up

back up [Music]

[Music]

[Music] there we go microphone in the vacuum

there we go microphone in the vacuum

there we go microphone in the vacuum chamber with the speaker outside the

chamber with the speaker outside the

chamber with the speaker outside the vacuum chamber now I want to try putting

vacuum chamber now I want to try putting

vacuum chamber now I want to try putting both of them in the vacuum chamber with

both of them in the vacuum chamber with

both of them in the vacuum chamber with the cotton balls and then pulling the

the cotton balls and then pulling the

the cotton balls and then pulling the air out and I think I might actually try

air out and I think I might actually try

air out and I think I might actually try letting the sound run as the air pulls

letting the sound run as the air pulls

letting the sound run as the air pulls out so we can see if it just slowly

out so we can see if it just slowly

out so we can see if it just slowly drops off as we run out of air give a

drops off as we run out of air give a

drops off as we run out of air give a shot speak here in here make sure it’s

shot speak here in here make sure it’s

shot speak here in here make sure it’s not touching the walls microphone in

not touching the walls microphone in

not touching the walls microphone in there all right there we go

there all right there we go

there all right there we go we’ve got both of them in there let’s

we’ve got both of them in there let’s

we’ve got both of them in there let’s get the sound going and then start

get the sound going and then start

get the sound going and then start pulling out the air and see if we get

pulling out the air and see if we get

pulling out the air and see if we get that sound to just seem like we’re

that sound to just seem like we’re

that sound to just seem like we’re turning down the volume knob

turning down the volume knob

turning down the volume knob [Music]

[Music]

[Music] [Applause]

very quietly I can hear if I touch my

very quietly I can hear if I touch my ear to the Plexiglas like really press

ear to the Plexiglas like really press

ear to the Plexiglas like really press it on there think I can even hear it a

it on there think I can even hear it a

it on there think I can even hear it a little bit with my ear on the glass

little bit with my ear on the glass

little bit with my ear on the glass itself this time super quiet though

itself this time super quiet though

itself this time super quiet though alright let’s let the air back in while

alright let’s let the air back in while

alright let’s let the air back in while it’s still playing see what kind of

it’s still playing see what kind of

it’s still playing see what kind of result we get

all right there we go

all right there we go both the microphone and the speaker in

both the microphone and the speaker in

both the microphone and the speaker in the vacuum chamber at the same time

the vacuum chamber at the same time

the vacuum chamber at the same time pulling the vacuum while it’s playing

pulling the vacuum while it’s playing

pulling the vacuum while it’s playing music so hopefully we can hear the sound

music so hopefully we can hear the sound

music so hopefully we can hear the sound diminishing as it loses the ability to

diminishing as it loses the ability to

diminishing as it loses the ability to transfer the sound through the air now

transfer the sound through the air now

transfer the sound through the air now I’ve had a chance to go and listen to

I’ve had a chance to go and listen to

I’ve had a chance to go and listen to the sounds that the microphone recorded

the sounds that the microphone recorded

the sounds that the microphone recorded while the microphone and the speaker

while the microphone and the speaker

while the microphone and the speaker will both inside the vacuum chamber with

will both inside the vacuum chamber with

will both inside the vacuum chamber with no air I really thought that the sound

no air I really thought that the sound

no air I really thought that the sound is gonna be almost nothing that it would

is gonna be almost nothing that it would

is gonna be almost nothing that it would be almost completely silent but the

be almost completely silent but the

be almost completely silent but the microphone managed to pick up quite a

microphone managed to pick up quite a

microphone managed to pick up quite a bit of the music from the speaker so

bit of the music from the speaker so

bit of the music from the speaker so something in that chamber is still

something in that chamber is still

something in that chamber is still vibrating enough to get the sound from

vibrating enough to get the sound from

vibrating enough to get the sound from our speaker to our microphone there you

our speaker to our microphone there you

our speaker to our microphone there you have it playing sound and music inside a

have it playing sound and music inside a

have it playing sound and music inside a vacuum chamber we tried a whole bunch of

vacuum chamber we tried a whole bunch of

vacuum chamber we tried a whole bunch of different varieties with the speaker or

different varieties with the speaker or

different varieties with the speaker or the microphone inside the chamber

the microphone inside the chamber

the microphone inside the chamber outside the chamber both inside the

outside the chamber both inside the

outside the chamber both inside the chamber and I think we got some really

chamber and I think we got some really

chamber and I think we got some really good results and luckily for us our

good results and luckily for us our

good results and luckily for us our microphone does still function in a

microphone does still function in a

microphone does still function in a vacuum that was good to learn this has
