The Stuart onset is brighter in tone than the Steinway. The spectrogram below shows the Stuart fundamental, 2nd and 3rd partial frequencies each have higher peak volume levels, at the onset. The onset of the Stuart fundamental is observed to be decaying faster in the onset to .5s. and then at .5s to transfer to a significantly slower decay
The energy curve below, shows the earlier transition of the Stuart sound, from the onset oscillation (i) to the after-sound oscillation (ii) , indicated by the change in the decay rate.
The Stuart sound also arrives at its 2nd phase after-sound oscillation (iii) earlier than Steinway (iii)
The Stuart sound sustains significantly more than the Steinway sound, between 4s- 8s.
