soundboards, gongs, drum heads and speaker cones

[Farrell]

An excellent set of references would be all articles written by Del Fandrich and published in various issues of the Journal of the Piano Technicians Guild. I don't have a list of which articles are in what issues - perhaps someone else on the list does. You can purchase a set of CDs from the PTG with all the back issues of the Journal.

Another reference might be "Piano Tone Building" by Del Fandrich - also available from the PTG.

> Where can I learn more about how the soundboard handles vibration? I see that a soundboard curves upward and that strings might be exerting a downward force. So the event of a hammer hitting strings produces a vibration that is carried to the soundboard that amplifies the sound we hear.
> 
> What I am asking for are relevant references to the physics of how the soundboard handles vibration. So far I have reviewed a seminar given several years ago at the Swedish Royal Institute of Technology.  
> 
> I am particularly interested in speculating that the function of a soundboard is similar to that of a gong being struck directly by a hammer.
