Subject: BS: Finding the Q spot
From: GUEST,Richard H
Date: 26 Dec 04 - 11:15 PM

I was practising a newly-acquired soprano sax this morning and hit a rather impressive high D which I sustained.

Suddenly there was a terrific explosion in the kitchen. A one-pint glass had shattered into little pieces none bigger than 1/4 inch. My wife says the individual fragments continued to vibrate furiously for a while afterwards.

I've heard of shattering glass with your voice and found the following on the Net: "The likelihood of the glass shattering increases with the Q value for the resonance of interest. You can tell what the resonant frequencies are by just hitting the glass with a fork (I do this at parties all the time) and the Q value would be determined by the length of time the tone the glass makes takes to decay till you cannot hear it any more."

I know about the G-spot on a soprano (that's where Kenny plays) but don't have a clue about Q value or resonance of interest.

The glass hadn't been in a microwave and was last used about 2 hours before. It had no cracks or chips.

Could the sax have shattered it?

The fact that the glass shattered is due to the fact that the fundamental frequency, or possibly one of the overtones, of the note played by the sax is equal to the mechanical resonance frequency of the glass (or at least damn close to it). So, the soundwaves travelled through the air from the sax to the glass and set the glass to vibrating at its resonant frequency which means that the motion of the glass continues to build as it is stimulated until it comes unglued.

The Q factor is the Quality factor of the glass. This is a measure of the sharpness of the resonant frequency. High Q means a sharp resonance which responds to a narrow range of frequencies but gives a bigger response if stimulated in that range. Low Q means that the range is wider but the response is less.

FWIW

Glass is not a solid. It may look like a hard shiny surface to you and if hit it will shatter.   So will toffee and tar. It is all a question of temperature.

Glass has no latent heat of fusion, it is what those in know call a supercooled liquid. This may have some bearing on the effect - so will the surface tension that builds-up when it is so far below its pliable temperature.

Not a lot of people know that.........

The fact is that everything solid has its own frequency and if that frequency is reached sonically something will happen to it..even shattering. When someone scratches their fingernails down a blackboard...what does it make us feel....they are reaching our frequency and our brains react by making us cover ears etc. This phenonenom was used to torture prisoners in the Second world war and subsequent wars by means of electronic equipment.....Nasty devices.

after viewing that website, I found my ethereal cosmic consciousness had been transduced into a state of boundless disrhambic chakras, vibrating in harmonious conjunction with acoustic fields derived from channeling Edgar Cayce while listening to the Beach Boys in a geodesic dome inside a pyramid which had been oriented toward the confluence of spiritual energies emanating from celestial manifestations of massed sensory nodes inherently located within my own attempts at focused spiritual enlightenement.

What a revelation!

Dave, that's what I thought it was about. Now Bill's channeling Edgar Cayce (and probably Jeanne Dixon), the Beach Boys (and probably the Rolling Stones played backwards), and now the gates of Hell may open when he gets to Mother's Little Helper. He's speaking in tongues (because I don't think what he wrote above is English), and the whole known universe could be in real trouble here. I mean, the only thing worse is getting your electricity supplier mad at you when they make a mistake on your billing and tell you you owe $739,421.93 on your November bill and they don't want to hear that you didn't use that much electricity in your two-bedroom house with no cyclotron in the basement.

John had his John had revelation and now Bill's having one, too. It's time to get a little nervous here.

Hi

My tuppence worth is that the Q in frequency is not the quality of the glass (as in Bev's and Jerry's above) but is the efficiency of the delivery of the frequency.

We see it (Q) being used to develop Rf systems in plasma and communications generation and how it applies to transmission of a frequency into a load such as an aerial for broadcast or a chamber for plasma generation etc. In practical terms the higher the Q value (through some maths that I don't understand) the more efficient the delivery of the frequency.

If the frequency you were playing was poor or varied, the build up of harmonics in the glass would have been inhibited or at best - varied, but as the delivery was more efficient, the harmonics developed were sustained long enough to shatter the glass by basically vibrating it to bit's.
A note - if the glass was cracked it may have been more difficult to shatter due to the crack interferring with the resonations.

Diesel:

We did not mean to say that Q is the quality of the glass. It's the "quality factor" of the resonance curve of the item made out of the glass.

We also are more familiar with "Q" in electrical terms but it has an analogous meaning in mechanical terms. We have no idea why it's called "quality factor" but it is.

Listen up, you people. I'm into goats for a living. But play a lot of music on the side. It means a lot to me, especially sax.

Before this happened, my wife enjoyed me taking out my gleaming 27 inch long soprano and performing lustily. Now she's scared stiff.

The replies above are great but a bit above goat-farming level.

The point is, my sax life has been shattered. And I need fellow-musicians to come to my rescue and state unequivocally (if that's the right word) that I could NOT have wrecked that glass.

I mean, I sometimes play in high-class hotels. Can you imagine what would happen if Tony Blair (who comes our way now and then) was having a drink and BOOM!!?

The frequency and delivery efficiency of sax to my resonant curve sure makes a difference to the G spot in this alto, so I assume it works for sopranos also!

Q is all about transferrence of energy, at resonant frequencies Q is measured in Electrical terms as the ratio of "current in" (parallel ccts) to circulating current. There is preferrential gain in the frequency domain. Max gain and resonant frquency differ by a factor which also determines the value of Q - the losses in effect. In mechanical terms it is movement, move glass too far and it breaks.

in answer to your "likes" - is it because you can get a tune from G and only harmonies from Q's?

Stilly River Sage you are one bright, brave lady with a very good sense of humor.

Since I am not as bright, and my humor is somewhat "spotty", I will let the rest of you ponder the real meaning of the Q spot, notwithstanding its potential electrical resonance being inductive or capacitive reactance or neither.
