I think you're having the same problem plenty of other people 
commonly have, in thinking of string energy as sound. It's 
not, even though a very small part of what's there produces a 
faint sound. It's not sound when it transfers to the board 
either. It becomes the loud  piano sound when the board moves 
air and we hear the result. Sound is a manifestation of 
energy, but energy isn't necessarily sound. You can't hear 
light, even when it's at a high enough energy level to fry 
you. In that case, you can smell the BBQ. But a light beam can 
transmit what is translatable into  sound at the receiver, 
either by analog modulation, or digital pulses.
