[Paul McCloud]

The soundboard may have lost its crown, and the springs may be a last ditch attempt to restore it, as some have done with valve springs.  The result would be as David described, ie., more sustain and less attack.

It won’t actually make the sound louder.  Stiffening in this manner is an attempt to improve sustain (usually).  More stiffness means less loudness, at least at attack, but a slower rate of energy loss, i.e. more sustain.

Wim,
It looks like the glue joints between ribs and soundboard are good. There are some cracks in the sound board but not very wide.  I suspect they may have been put in there to "bolster" the sound (increase the volume) as it was in a retirement home - you know - older people and their ability to hear has gone down!!??   That excludes us older tuner/technicians!!

Does it look like original equipment, or did someone put pedal springs between the ribs and beams to stop some buzzing?
