Thanks for this! Your videos are always so intriguing. It's amazing to think that those notes you made were the results of someone's concept on how a sound would be written a long long time ago and like all knowledge, we've just built upon it from there. It's also crazy to think that the people in the middles ages and probably long before knew all this about these sounds and frequencies and used that to build bells and other wonderful instruments and write beautiful music. But not everyone knew thing, it was likely a more well kept secret and only the top 1% participated. Thanks to the internet, things like RUclips and people like you we all can learn and at least reach a decently high level of thinking and understanding of the world.
Thank You!!! The metal bell of a balanced mix of metals sounds so nice !!! This means that the pressure of the beater is on the bell and the buzz is on !!! And location to place varies depending on its climate !!!
Hey prof, I study psychoacoustics for fun, and something you said struck me (ha!) as odd. You referred to the undertones of a bell, and I always learned that undertones were physically impossible to produce through resonance (aside from one interesting violin technique). Pitches below the fundamental aren't part of the harmonic series. I started looking up bells and undertones and found very little until I found a paper on "virtual pitches". Apparently, bells have undertones, but those undertones don't correspond to any physical process, but are rather a purely psychoacoustic phenomenon. Your brain puts it there when trying to make sense of sounds that aren't perfectly accurate harmonic series. Definitely something to look into!
This was really interesting, sound is not a pure sinewave there are different waves combined like the cats meow has a hidden undertone that is the same pitch and frequency as a human baby's cry ... them cats are alllll about deception =^.^=
To get the overtones and undertones right, the mass has to be distributed perfectly. So the people who make and shape these bells are *massters* of their crafts XD 5:30
Same as the first one -- but no one ever seemed to find it so we are doing some featured re-releases to highlight some of our "hidden gems". We are scheduled to shoot brand new content later this week. Not sure how long post-processing will take....

If I would of had teachers like this, I would of continued my education. So I’m continuing now! Thank you!!!
If I had teachers like this ...
george melke yes there is finally access to world class professors for free on RUclips
But I would like to hang out on the campus and learn from different people's
"How Sound Works *and Why Bells Sound Good* "
"Guess what?! I got a fever, and the only prescription is more cowbell!"

3:00 UUUUuuuu 😂😂😂 I love this channel
The Ruzic capella trio.
Started watching this channel out of curiosity about nuclear energy and accidents. Now this, what a turn. 🙂
I love this youtube page. So much info on so many different things. Thanks for all the time you put into making these videos! I appreciate it.
The Sound of Physics!Pitch Perfect!
Ah, memories of the Engineering Campus in the 1980s, with the Altgeld Hall Carillon playing...
Thank You!!! The metal bell of a balanced mix of metals sounds so nice !!! This means that the pressure of the beater is on the bell and the buzz is on !!! And location to place varies depending on its climate !!!
Thank you. Interesting and informative. I always enjoy your presentations.
Sounded like they had the ‘ Westminster’ chimes going in the bell tower. Enjoyed the video.
Meme researchers can find quality stuff here, apparently they are not aware of this channel yet!
i got a fever! and the only prescription is more illinois energyprof!
"What makes a sound good ?" I half expected Vsauce music to start playing
@D.O.A. old Vsauce was pretty good but new Vsauce is not half bad in my book
You make the best videos. Keep them coming
Judging by the comments I see the inspiration for getting new markers, great video as always.
Very interesting lesson as usual. Thank you very much. Happy Christmas
Altgeld rings my bell, because I just red the book "1900 or the last president"! 😂
“Sound appealing” when talking about bells. I don’t know if that was intentional - but bravo.

Beautiful singing voice 😩

Can you please explain how sonar and radar works ? Thx for all your effort professor !
20k subs already! Soon we will have 100k !
0:58 "Hey, I'm sounding here!"
What about annoying sounds like chalk on a chalkboard? Or squeaky markers on glass! 😁
How is this not at the top? 😎

UUUuuuuuu 🎶🎶🥰️
Ding!
Dong!
@@GoatzAreEpic Dang!
Dung!
But professor can you answer this?
A piece of polystyrene foam rubbed on a pane of glass.
Why does just Imagining it hurt my ears?
Are there any differences between this video and the original release? I have no comment on the tie today....

@@illinoisenergyprof6878 Fantastic!! I need some great content while waiting for season 4 of Rick & Morty to come out on blue ray.
Bell metal is bronze (Cu, S.N.) not brass Cu , Zn). Brass does not sound as good. Why?
You may think bells sound good but I had to live with a herd of god botherers ringing their damn bells every Sunday for years. Bells, I hate 'em.
Cu, Sn ( spell checker boxes not know chemistry
lol annoying sounds.... like whiteboard marker squeaks on glass. haha
Speaking of annoying sounds how about your marker?
Please consider the horrible sound the marker makes as you write on the glass. A engineer that cares would be able to cure the problem.
Too much talk, long winded. So little information. I want to see a demonstration not just a person talking taking and talking. Boring.
