[CAUT] Accujust and grunting fish bait

[David Love]

Thanks, I understand what a transducer is and all the mechanics.  I don't
need it simplified I'm looking for the more precise scientific language but
I think it's enough already time to go directly to the engineers.

David,

The best way I came to understand this is the old tin cans tied to a wire
"telephone" I made as a kid. You talk into one can and 50 yards away someone
else hears it. No new energy is created, but the sound travels along the
wire and the can is the transducer. There is some signal loss, by heat or
impedance, etc. but the sound is not "amplified" by the tin can, per se.

Maybe too simplistic, but that's how I see it.

OK. I'm not trying to be a pain here so please bear with me as I wrestle
with the correct terminology (I do get the mechanics).  If we hammer on a
string that is not connected to a soundboard we hardly hear it.  When we do
couple it to a soundboard the energy output can actually damage our hearing.
How is that reconciled with either no new energy is created or the output of
energy is not increased when we consider sound as a form of energy.  Isn't
there such a thing as a mechanical amplifier?
