i wonder if Tseung will take the time to scroll down on the page above to the section marked "Electrical power".....and.."Instantaneous electrical power"..and,,"Peak power and duty cycle" ??

if he does...maybe he might see the error of his ways

i remember a song which goes like "James brown is dead" it was a hit here in the early 90's.
i'm thinking about a reamix which goes like this:

"Lawrence Tseung is a Clown" tuu tuu tuu tuuduuduu tuu tuu
"Lawrence Tseung is a Clown"

                            A second tuning fork Intensifies and Prolongs the sound emanating from a first tuning fork.

You say,
The Dictionary says,           
If you INTENSIFY a Sound Wave... you are 'increasing the magnitude or strength' of the Sound Wave.

                                                         E=I/c

                                                     E= Energy
                                                     I= Intensity
                                                  c = speed of sound   
           
Fact --> The Energy of a Sound Wave is Directly proportional to it's Intensity.
If you make a Wave more Intense and Prolong it... you are adding energy to it.
The Formula does not lie.
-----------------------------------------------------------------------------------------------------------------------------------------------
Please consider the Common Physics Experiment below.

1. Speaker emits a Tone.
2. A microphone picks up the Intensity of the Tone. (this is recorded)
3. Test tube water level is adjusted until a 'Loud' Sound is heard. (observe Test tube Vibrating now)
4. Get another Intensity Reading from the Microphone.
5. Compare Intensities from #2 and #4.
6. Use above formula to calculate & compare the Energy Difference between #2's Wave and #4's Wave.
    The     Ratio of  #4 / #2     is the Gain.
-----------------------------------------------------------------------------------------------------------------------------------------------
Finally you say,
I don't need to buy any tuning forks, my acoustic guitar has 7 of them.
I have done the experiment and it confirmed the assertion made by the Dictionary.

5. Acoustics - Intensification and Prolongation of Sound, Especially Musical Tone, Produced by Sympathetic Vibration.

I do appreciate your time on this.

Sound intensity is defined as: The sound power per unit area.

A microphone does not measure sound intensity, rather it measures sound pressure level, or SPL. This may make the energy test and calculation invalid. You need sound pressure and particle velocity to obtain sound intensity. I = p x v.

A higher SPL reading on the microphone does not mean that the particle velocity did not decrease, because you have not measured it. CoE implies that the particle velocity would decrease if SPL increased, in order to maintain the same energy.

Don't confuse resonance with a systemic gain in energy, because it is not. What you are observing is a more efficient transference of energy from one place to the other, and back again. This does not imply that WORK is being accomplished in the process, because it may not be. It depends on the "load" seen by the "system".

For example: The charge stored in one capacitor can be efficiently transferred to another capacitor of equal value via a low loss inductor, and this transfer can occur back and forth and be "prolonged" for quite some time, indefinitely if the inductor were completely lossless. However, if there are no losses or "loads", there is absolutely no work done in the process.

With two tuning forks, there is air resistance which is lossy (i.e. a load), and the fact that unless the tuning forks are separated exactly by a whole multiple of the wavelength, there will be destructive interference between them.

There is a whole lot more to this than you may realize, and you have not come forward with what your ultimate point is in all of this anyway? Surely, you are not implying that two tuning forks in resonance is a free energy device, or that free energy can be extracted from it somehow?

ahh poynt...the sound of sensibilty
