The Stuart piano strings and soundboard have produced a wider, louder spectrum. The Stuart sound is 9dB lp and 8 dBA louderthan Steinway at mic 6.The Stuart has a more full- bodied round sound, with greater bass frequency tone, and more prominence of the 2nd, 3rd, 4th 5th & 6th partials. With longer and thicker bi-chord strings, wrapped in stainless steel, higher higher yield capacity set at significantly higher tension, and with the soundboard vibrating 52% larger amplitudes of significantly the 2nd prt. The Steinway has a brighter thinner tone.
The Stuart piano sound, decayed at a faster rate than Steinway, in an exponential decay of amplitude246, from a significantly louder onset. At 3s, the Stuart rate of decay slowed momentarily for 1s, similar to the Stuart decay curve at mic2.
