Sound Waves and their Sources (1933)

[dag451]

What a wicked little vid, this does a really good job of demonstrating some of the physics of sound. Thanks for uploading.

zzzzzZzzzZZZZ....Oh silly me

[DjVinnie91]

at 0:09 it says "Copyright MCML..." MCML is 1950, not 1933.

[dag451]

@DjVinnie91 You are right actually. But it also says 'second edition' so maybe the first edition was 1933.

[MobYardieKrew]

im only watching this because soundrone liked it

[jeffharms]

the whole "lower fork" part is confusing. The "lower fork" here has the higher frequency and higher pitch.... although on my computer, the upper fork SOUNDS higher (I am maybe hearing a high overtone higher than the intended pitch. Either way, it is confusing. Low pitch = low frequency.

[emilang]

no need to go to lectures anymore

[ambroisebellec]

I watched this out of interest ! usseful for understanding synth programming

[115breno]

@ambroisebellec im here for the same reason

[1Rprprp]

this will help me with my homework!!!!!! lol

[benthemiester]

Thanks for quantifying the science of sound Bell labs.

[kenedi62]

believe or not our teacher took this video for teaching us in our physics class . I saw your channels name and came home then i am revising it !

[ronalddiaz]

i thought that sound is in a form of longitudinal wave... this vid is showing transverse wave

hw du u dowmload d video need fr a physics project

[music2012]

@thekingofpopMJ100 There are many addons for firefox like download helper that can do it.

[HorizonDelta]

Good video. More tech in "Wonderful electric energy" by HorizonDelta ;-)

[teamascii]

Apparently this version comes from 1950 (it's a second edition)

[antoniomelike]

Yes, now I'll ace my physics test.

[DrShpilev]

1933, but pretty good and accurate.

[MrVevoVEVO]

@DrShpilev

Where do you think we got it from?

[DrShpilev]

@MrVevoVEVO

I don't quite understand you.

[MrVevoVEVO]

@DrShpilev

You said "1933 but pretty good and accurate" I assumed you meant they wouldn't know about this kind of thing due to the time period they lived in.

And my reply was that we have this knowledge because of them. ;)

[DrShpilev]

@MrVevoVEVO

Well 1933 was also the time of reefer madness so it's hard for me to take any old American documentary/PSA seriously.

[cumesoftware]

Very accurate indeed!

[LGreen1995]

Am I the only person here who is watching this for school and for fun?

[aubrey0610]

can i download?

[TheFriedFrog]

wow...this is before ww2! Good explenation though ;)

[MrVevoVEVO]

@TheFriedFrog

They had knowledge of this before we did, obviously. ;0)

[toncookie337]

MY BLADDER WON'T CLOSE!!

[Henrikkove]

WOW! This was boaring :p

[domyaska]

thanks a lot for sharing !!!!!!grazie mille

[lordofblackness]

This has been quite useful in my revision. Thanks for uploading this!!!

[royalsteven]

1.30 Focus focus you're getting sleepy....yes master.

[Bgt2008]

Thank you very much. This video is worth a thousand pictures.

[OnceForAll]

That is called CYMATICS

Rearrange matter with sound vibrations...

This video is different, but it comes down to the same thing, maybe even better.

However this has been known for a very long time, only the knowledge has been surpressed for the mainstream public, obviously...

Because who is going to pay for energy when it is extraordinary cheap or even for free... The BIG Company's don't like this at all... That is why we have to use internet for spreading the word, but beware a lot disinfo !

[kierensleight]

I am only watching this because i am board in my science lesson lol

[CywDryw07]

thank you so much for this video. it has helped me to revise for physics tests!! =]

[gyshalom]

thank you very much for uploading this film!!! i finally got the answers i was looking for!!!

[photopicker]

this is a really well done video!

[Watercolordragon]

GREAT!!

[BlakeMason2]

Seeing that EB logo took me back to elementary school in 1977. WOW. Remember film strips? hehehehe.  I like cool science movies like this. Thanks for posting.

[CjDob]

So good!

[PeterInglisGuitar]

An excellent introduction to the physics of sound. The mechanisms explained here form the basis of -all- music making.

At 6:00 the overtones produced by a vibrating string are explained. Understanding this opens the way to producing different timbres from, for example, the guitar.
