Why is an Acoustic Guitar so much LOUDER than an Electric Guitar?

[The Observer]

Swimmingcat,

     To understand that a speaker is overunity you need to understand Anisotropic Energy & Magnetic Permeability
          and how they pertain to ferromagnetic materials.

     In short, when a coil is wrapped around a piece of iron..
         the resultant magnetic field is
                      The Coil's Magnetic Field + The Iron's Magnetic field.

      And the Iron's magnetic field is 5,000 times that of the coil !!!!!!!

       I appreciate your rant...
                                          I think alot of people are skipping the basics.

                   That's why I am emphatic about this Resonance Thing.

Paul,
        Although a machine to do some strumming would be cool,
               It is undeniably true that an acoustic is much louder than an electric.
     
       However you brought up such a great point.
            National Guitar...
                   I discovered this last night when doing research.

      For those of you that don't know, In the 1920's they made super duper
         loud Acoustic Guitars because of problems of the band overpowering
            the guitar before electric amps.

      http://en.wikipedia.org/wiki/Resonator_guitar

      You know what they called it?

       A Resonator Guitar.

       hmmm... they made it louder by doing something with a Resonator !

      No kidding?
     
I'll be back,

Utiltarian... from page 1 of this thread,

The sound is amplified, but the energy is not.  Without the soundbox of the acoustic guitar, the energy in the vibrating string would simply escape in another fashion.  With the soundbox, much more of the energy is converted to audible (and audibly pleasing) sound.  The soundbox does not magically amplify the energy, though; that would be impossible without some type of other input of energy, such as an electric amplifier.

You state the sound is amplified, but the energy is not?
             
          1. Higher amplitude waves come from a larger energy source.       

You mention the energy would escape in another fashion?

         2. Everything is the SAME except for the Acoustic Resonating Cavity.

You assert the sound box converts energy to audible energy.

         3. The sound box is actually an Acoustic Cavity Resonator.

On a side note. I stopped by the book store and read some Tesla books.
I was interested in exactly what he was going to do with Wardencliff.
Apparently there were going to be many uses, one of which was Free energy for all.
Wardencliff was actually smaller than the worldwide version, but in short...

Tesla wanted to put a radio frequency out that would Resonate in the Schumann Cavity ( a very specific frequency ).

That is , a small driving force (the tower) would cause a large oscillation in the resonator (the Schumann Cavity).
This large oscillation would then be tuned into for free energy by "large radios" dialed into that frequency.

Or using the guitar analogy...

          The Wardencliff Tower is the String.
          The Schumann Cavity is the Body of the Guitar.

I made an important discovery.

This discovery proves that two similar tuning forks (1 struck, 1 not struck) ring for a longer period
        than the case with just 1 tuning fork.

            This proof is important because naysayers and Wiki pages say the opposite is true !

1. Take an acoustic guitar and tune it perfectly... with a tuner if you have to.

   2. Strum the High E String.

     3. Damp the High E String.

       4. Observe an E still ringing.

5. Observe that the Low E and A Strings are vibrating. (Two Strings that were Not Plucked !)

6. Strum High E Sting with all other strings Damped.
 
    7. Time the length of sound from High E String (~6 seconds)

       8. Strum High E String without Damping any other strings.

          9. Time length of sound from High E, Low E and A vibrating... (~ 12 seconds !)

One final point is that it is louder with all vibrating too, however I havn't tested this with a decibel meter for definitive proof.

Please try this at home, this is reproducible proof that Free Energy exists in Forced Resonant Systems.
   It will happen every time, as long as the guitar is in tune.

                  Please let me know how this turned out for you. ;o)

The acoustic guitar's body is designed to couple to ambient air
better then the electric guitar which is designed to couple better
to an electronic pickup. But...the resonant box of the acoustic
guitar is going into interfere with a number of "hot licks" and
offset tuning of an accomplished musician. So the acoustic
guitar is louder...but not necessarily better.

Which is louder; A big cone speaker in an acoustic chamber cabinet
or small cone speaker when driven with the same signal?

I recently posted this response to someone else's statement about resonance:

The statement:

Shortly : ask yourself , how RESONANCE is at all is possible ? When you struck a rod at correct frequency and it sings very long - isn't that an unexpected miracle ?

The reply:

It's not a miracle because it's the same resonance ring-down that you see in an RLC resonant oscillator.  The stiffness of the rod is like a spring, and that represents the size of the coil.  The mass of the rod is like a capacitor - the speed of the moving mass is like the voltage across the capacitor, and the amount of mass is like the size of the capacitor.  The fact that the rod does not sing forever, is because there is some energy lost in the mechanical hysteresis loop of the rod.  This is like the resistance in the electrical RLC resonator.

When you hit the rod you put energy into it.  The rod stores that energy by singing.  The stored energy goes back and forth between the moving mass and the compressed spring.  When the mass is moving its fastest, the spring is completely decompressed, and all of the stored energy is in the moving mass.  When the mass has stopped moving, the spring is at it's maximum compression, and all of the stored energy is in the spring.

Just like in the electrical version the energy goes back and forth between the capacitor and the coil.  When the capacitor voltage is at it's maximum, there is no current in the coil, and all of the stored energy is in the capacitor.  When the capacitor voltage is at zero, there is maximum current in the coil, and all of the stored energy is in the coil.

So in both cases, energy is just going back and forth in a nice smooth sine wave pattern.  Resonance is just energy smoothly moving back and forth between two things that can store the energy.

At the same time, the form of the energy is always transforming back between two different states in a sine wave pattern.  In the above examples the two states are a moving mass and a compressed spring, and a capacitor with voltage across it and a coil with current going through it.

That is the key to understanding resonance and it applies to almost anything that resonates.  If you don't understand it, it is worth reading through until you do understand it.  The prize is five Brownie Points.

"Forced Resonance" would more aptly be described as putting energy into the resonant system, and then watching it decay out of the resonant system and transform itself into other forms of energy.  There is no over unity there, but it is a fun and fascinating study.

Can anyone see how this applies to the acoustic guitar example?
