Eight Introductory Sounds of Stuart Piano Tone Distinction.
1. C5v54 MW mic3Onset Tonal Stability.; Slower Fnd a-s; Earlier a-s transition.
The Stuart sound is brighter, with more sustain of the onset tonal balance. The Steinway decays immediately and has a rounder tone. The Stuart’s larger Fundamental, 2nd and 3rd partials, contribute to the brighter tone colour.

The brightness of the Stuart tone at mic3 is enhanced in the room sound of the 8 microphones.
Decay:
The Stuart sound decayed more rapidly in the onset state (i) for a shorter duration, losing less energy in the onset, with its earlier transition into the 1st phase of the slower settled oscillation (ii), a phase of decay observed as being less significant in the Steinway sound, in this instance.

Both pianos radiated waves of similar SPL to mic M19 (STU) lp 83 leqA 62 ; STE lp 82 leqA At velocity 54, Stuart radiated waves of its maximum SPL to mic2, and Steinway radiated waves of its maximum SPL to mics 1 & 6. The Stuart sound radiated marginally higher SPL of C5 to mics 2,3,5,7 and significantly higher SPL to mic 8.Soundboard: The magnitude of the movement of the Steinway soundboard was found to be 46% higher than the Stuart soundboard for C5v54. |
