| Sound table 4.35 | |
The Stuart is 4dB louder, with a larger in amplitude onset harmonic spectrum, of the Fnd. 2nd, 3rd & 4th partial frequencies.. The Steinway sound colour changes tonally and in amplitude at approximately .5s. The spectrogram below shows a moderate increase in Steinway’s 4th prt. amplitude at approximately .2s. The onset attack is marginally slower in the Stuart sound, followed by a dramatic rapid decay of the fundamental and 2nd partials between .2-.6s.

The spectrogram plot of 3s below, shows the Fnd. and 2nd prts. to be sustaining and decaying at opposite periods. At .8s, the Stuart is in rapid decay, whereas the Steinway is steadily and at 1.5s, the Stuart Fnd & 2nd partials sustain their levels at 1.5s, whilst the Steinway decays more rapidly.

The decay curve shows a typical pattern of Stuart sound, a faster onset decay 0-.5s (i) , and an earlier transition into the slower after-sound oscillation, signalled at 1.5s (ii)
