does glass make sound?

[CitizenNot]

would life exist without sound? just curious to know how music and sound influences everyones artistic abilities and work habits and everyday life around glass.

[NUBBLET]

I hear music even when its not on , and sometimes dont hear it when I get into something even when it is on .

has anyone ever had the glass sing to you ? I think its from moisture getting to the hot part of the glass , and a "tea kettle" type effect , letting out a hum . It also resonates at a certain pitch , if you can hit the pitch just right and loud enough you can break glass with an unaided human voice . I think Mythbusters did it , but there was a show on that had some singer break glass by voice

My glass talks to me constantly telling me things like - stoopid - I'm not hot enough yet or yeah, that's it - keep doing that :lol:

Singing points are not from moisture, but that is the most common explanation people give.

what about cymantics? (spelling?) molten glass in a crucible subjected to various sound vibrations? powdered graphite works pretty well

one cool example of singing glass is Benjamin Franklin's Armonica... boro and probably made on a lathe...apparently it was his favorite invention http://fi.edu/franklin/musician/images/armonica.jpg

Not boro.
There is audio on the harmonica page.

they still makle those in mass outa boro or quartz... at finkenbiner ... im pretty sure its called sci glass place

"would life exist without sound?"

Alot of deaf people are scratching their heads at that question. And I am too. As much as I love music and the ability to hear things, my life would continue if it went away tomorrow.

My glass likes to sing that "chk chk chk" song when I'm working on it...

[e-jipt]

I don't have any music where I work. I had an mp3 player but I don't have the cord to put new songs on it. :(
I usally just sing really retarded made up shit over and over. Every 2 or so hours I'll change a few words and probably make it sound more retarded.
My girlfriend hates when I do this at the computer.

Brian , I ran across this (http://uw.physics.wisc.edu/~timbie/P325/Fahey_thermoacoustic_oscillations.pdf) page searching for sondhauss oscillations . It makes sense . I had just noticed the hum only when moisture was there ,along with a stoppage of the hum if I tilted the tube up so the moisture was not near the tip .Do you think it is a by product of the oscillations ? Or is it possibly the hydrogen and oxygen separation (from boiling) that creates a more vigorous oscillation ?Or is the moisture just there from condensation and have nothing to really do with it ? I am just fascinated with this topic .

[Brian Newman]

I believe the moisture to be incidental, it is certainly not instrumental (pun not intended, but noted...). I have downloaded that PDF, and will look at it in a bit.

that would make sense if all sound was able to be heard(and recognized) by the human ear. but its not. although your life would definately continue without being able to hear, life as you know it would be completely different without sound. sound waves are pretty much pressure waves and are responsible for much more than you think.

It has math that is beyond me. In another thread, Doug had mentioned wanting a simple tube to demonstrate the principal. Who is good enough with advanced math to figure out what length of a standard size tube will sing from say a standard tea candle?

[CitizenNot]

would the tubing be closed or open?

[Brian Newman]

Closed at one end. Basic Sondhauss oscillations.

[melter skelter]

isnt it the flame pressure licking at the lip of an open tube what causes glass to sing whule your working it ... like a wine glass effect.

I used to know this crew of deaf kids in Colorado that loved taking mushrooms because they would have intense aural hallucinations. Thay said it sounded like the universe.

[dislexei]

reminds me of this move All Gone Pete Tong. Dude was a DJ, lost his hearing, but he could feel the bass through his feet. Ended up still producing music even after the death of his hearing.

I've never seen it happen with an open tube, or even a closed one unless it was just the right shape. It seems to require a long thin blowtube, with a bubble at the end. Since I don't use points, it happens most often to me when blowing slide bowls on 9.5mm. Doesn't always do it but I love it when it does, makes me feel like that piece is special. :D I like it when a bub turns out with the whistling/hooting carb hole too, its just kind of an accidental bonus that happens sometimes.

[Tzonis]

I hear music even when its not on

I would recommend laying of the hard drooogs.....
