Notes were: 70, 49, 21, 20, 1. Different colours represent different amplitudes. (color legend on the right side, amplitudes are around +- 1e-4 mm on note 70 (hammer speed of 2m/s mezzoforte), +- 8e-2 mm on note 49) The designer can compare for example amplitudes on note 20 (first on bass bridge) and 21 (last note on long bridge) and adjust rib dimensions accordingly in the soundboard model to minimize differences in amplitude response. regards, B.
