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

spondini,

That may not be a valid test if the distortion was placed before the mixer input.

Both should be clean with no compression or any processing at all.

Also, monitoring over speakers will still impart some feedback (adding sustain) to the acoustic, so it's best to use headphones. In fact, monitoring the audio is not even necessary for this test, because we are relying on the VU meter to indicate the sustain to -60dB. We simply time this and compare.

that is not a proper test. how does turning an acoustic guitar into an electric one make for an apples to apples comparision? by amping an acoustic it becomes electric and therefore no longer acoustic... this is obvious. furthermore, you need a picking method that inputs a precise and repeatable amount of energy, as well as a listening method that involves more than a VU meter and your eyes or headphones and your ears.

DrunkCaptain,

You're obviously out of your element here, and because of your brazen attitude towards folks, I'm not even sure why I read and am responding to your post, but alas, I'll answer your questions in good faith.

This particular test as I understand by the last few posts, is to determine which guitar has the longest sustain, the acoustic, or the solid-body electric. Are we in agreement?

Now, amplifying the acoustic's piezo pickup or mic signal does not alter the guitar's ability to sustain it's sound, provided an acoustic feedback loop is not present, and we eliminate this by either not acoustically monitoring at all, or by doing so only over headphones.

The same goes for the solid-body electric guitar.

So we are using a visual instrument that measures "volume units" to indicate when the level has dropped from 0dB down to some chosen level such as -60dBu (almost dead quiet).

A precise picking method would be ideal, but with a few practice tries, for an experienced guitarist it would not be difficult to consistently achieve a 0dB peak strum for each test. However, as a way to increase the likely-hood of accurate readings, 3 or 4 strums/timings could be tried then averaged out to minimize this error.

The precision will only be a factor if after a few tests it is obvious that the two guitars have a very close sustain time to -60dB. Chances are however the two will be quite different, and if demonstrated consistently as such, the small error in strum energy differences can be ignored.

it is 'wilby', that is future tense. it is not 'is' nor 'was'... ::)

to suggest you know what my 'element' is is asinine. because of your presumptuous attitude you are the only expert in your little mind. it's not as complicated as it may seem, and from your proposed test it would seem science is not your element.

yes.

amping an acoustic makes it electric, i assume you will agree with that? i hope this isn't similar to our previous discussion where it took you several posts to agree that a sim is incomplete...
if sustain is sustain then why amp the acoustic? simply put, you are not comparing apples to apples regardless of whatever semantic game you wish to play again. find a more precise method or accept the fact that your proposed test is sloppy. as proposed, your test would be fitting for the mythbusters, but far from precise science.

same goes for the solid body electric.

i am aware what a VU meter is captain obvious. how are you timing it? with a hand held stopwatch? ::)
in your apples to oranges 'test' are you using identical pickups on both guitars? or are you suggesting that all pickups are the same ::)

a precise picking method is required. no ifs ands or buts.

you seem to like to ignore what doesn't agree with your opinion quite often...
There is no news. There's the truth of the signal. What I see. And, there's the puppet theater...

Pointy,
   Will rerun test with both through di box, no power to speaker, just using visual meter.

Wilby,
      Blah blah blah.  Makes about as much sense as your posts.
