[pianotech] Sustain

[Marcel Carey]

I'll risk my 2¢ here. I don't think it's only  an impression of more power that you get with voicing. I think that proper hammer voicing can really increase the amount of energy that goes into the string and soundboard system. Here is My reasoning.When the hammer hits the strings, what does it do? It's pushing the strings as far as it can. Now, if the hammer is very hard, the string's energy will be used to push it back. So there is a lost of energy in the string & soundboard system used just to push back the hammers after the maximum string deflection happens.Now, if the hammer is properly voiced, what it will do is compress itself while pushing the strings to their maximum deflection and use it's own compressed energy to push itself back from the string just before the string get to their maximum deflection. This should provide the soundboard with the most energy to produce the sound we are trying to get. But this happens in such a short amount of time that it would be difficult to measure, but results can be heard.Just my 2¢,Marcel Carey, RPTSherbrooke, QC> > Porritt, David wrote:> > That's been my understanding too that it is the> > _impression_ that the sustain is longer rather than there> > being any energy conservation done by the voicing.
