[CAUT] Accujust and grunting fish bait

[David Love]

Yeah, I understand that.  I guess we've beaten this horse enough for awhile.

Hi David,

A piano action could be thought of as a mechanical amplifier. The system of
levers actually increase the power and speed of the keystroke to the hammer
strike. 
The string without a soundboard focuses almost all its energy into vibration
(think hi speed videos we've seen). When attached to a large flexible panel
through a bridge, the energy is transduced into audio frequencies that our
receivers(ears) can hear. 
The energy in both strings is the same, it's just expressed differently when
given the opportunity.
Hope this helps,
DP

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?

No. We've just changed it from one form of energy to another form of energy.
That is what transducers do.

| Del (et al):
| 
| One final question for clarification because there seems to
| be something missing in the link here.
| 
| If we agree that no new energy is created, but that the
| energy from the string through transduction creates new sound 
| via the soundboard, and if sound is energy, haven't we 
| created new energy?
