A sound board moves more air than a string alone can. This makes the string sound louder. There are technical reasons for not calling this phenomon amplificaton, but if it sounds like a duck, its OK to think that when you put your tuning fork to the sb it is amplifying its volume. Try calling it transducing. Or consider this definition from Webster III International. "......obtain an output of greater magnitude through the relay action of a transducer." Actually if the sound board were "powered" in that its movement while caused by the strings was made greater by power from another source, that is what "true" amplification is all about. ---------- > From: Horace Greeley <hgreeley@leland.Stanford.EDU> > To: pianotech@ptg.org > Subject: Re: Fw: amp > Date: Tuesday, November 03, 1998 9:02 AM > > > James, > > At 07:27 AM 11/3/1998 -0600, you wrote: > >>If a soundboard doesn't amplify, what does? > > > The (really) short version is that the soundboard in a piano is > a tranducer.
