Pulsed DC Transformer with Embedded Magnets

[utilitarian]

The Tseung hypothesis that additional energy from the environment is brought in is scientifically acceptable.  The total sound energy of the system (tuning fork and tube of air) is more than that of the tuning fork alone. 

How can you say that?  As poynt and BEP explained, a decibel meter or whatever you propose to use is not an adequate measure of sound energy.  It is merely a measure of perceived volume.

You also make no effort to measure energy input.  So how can you say there is more out than in?

Poynt,

You said,

As with the acoustic guitar, the result is a louder sound, but for less time.

Nope.. you have not tested this nor do you seem to understand how the resonator feeds energy back to the strings.

The Dictionary's Definition is true... and that's good news.
5. Acoustics - An Intensification AND Prolongation of sound, especially musical tone, produced by Sympathetic Vibration.

                               --->  Intensification means Louder (more energy)  <---
                                                        &
                                 --->  Prolongation means Longer (more energy)  <---

I still would like to know... What would be a suitable experiment to find out if a sound wave is being amplified?

LT,

About the diagram.

1.Using a speaker tone for the source instead of tuning fork makes for a more reliable experiment.   
   a. When using a speaker, you will have steady tone (steady energy value).
         - This quells arguments about the energy in a 1st sound wave, since it does not vary.
   b. However, there will not feedback as the speaker will not store energy vibrationally, so prolongation will be less.

2. You could just use a speaker and few tuning forks.
    a. Vary speaker tone to confirm a frequency match (watch and listen to the tuning forks)
    b. Then, do the test with the decibel meter. (no tuning fork.. then with)
    c. There will always be a prolongation of sound, since the fork will ring after the speaker is turned off.

3. This all leads to my idea that Resonating High Voltage Transformers is a valid route for experimentation here.
    a. Please check out the following video...   http://www.youtube.com/watch?v=Zacait0vgCM

Thank you to everyone for you time on this,

Source of Sound Energy as explained by the Kinetic Theory of Gases.

I believe all physicists and chemists have learned the Kinetic Theory of Gases as part of their training.

The Kinetic Theory of Gases assumes that:

1.   There are many gas molecules colliding with the surrounding walls and with one another.  They are constantly in motion and each of their kinetic energy is given by the formula 1/2 mV*V where m is the mass of the molecule and V is the velocity of the molecule.

2.   The pressure exerted on the walls or containers is a result of the collision of these molecules on these walls or containers.

3.   If a gas is in motion, we can treat that more molecules move in one direction.  (With a solid, if it moves with velocity v, all molecules must travel together with the same velocity v as they are rigidly bounded to each other).

4.   This means we can actually use the kinetic energy associated with the gas molecules if we can induce more to go in one direction than another.

5.   Furthermore, because there is plenty of space between the molecules, we can compress or expand the gas (decrease or increase their distance of separation).

6.   A sound wave is an ordered compression and expansion of such molecules.  This pulsing action “produces an ordered motion” rather than the random motion of the gas molecules.

7.   The ordered motion leads-out or brings-in the kinetic energy associated with the molecules.

Such an explanation is perfectly logical and does not violate any Laws of Physics.

The Almighty has clearly directed us to the true understanding of resonance in sound.  The energy associated with a tuning fork and a resonance tube is more than that of the tuning fork alone because of the kinetic energy from the gas molecules.  We used some of the striking energy from the tuning fork to lead-out the kinetic energy of the gas molecules.  There is no mystery to the increase in energy!

As I mentioned at the beginning, that dictionary definition is wrong and you cherry-picked it because it supports your claim. Do a search at reputable sites and see how many definitions you can find that state prolongation AND intensification occur at the same time. It is an OR function, not and AND. Most say something similar to this:

2. (Acoustics) A prolongation or increase of any sound, either by reflection, as in a cavern or apartment the walls of which are not distant enough to return a distinct echo, or by the production of vibrations in other bodies, as a sounding-board, or the bodies of musical instruments.
