C3 v20 MW mic3
Soundboard: The Stuart Fnd and 2nd prt. were resonated strongly in the Stuart soundboard. Steinway soundboard vibrated a wider spectrum of upper partials than Stuart. STU: Fnd.; 2nd ; 3rd; STE: 4th ,5th ,6th 7th Overall, at v20, the Stuart soundboard vibrations were 31% larger in amplitude than Steinway, for the note C3.
Instrument Volume Mic7: STU 86dB , STE 85dB
String Scale: For the note C3, the diameter of the Paulello/Stuart wire is 25mm thicker, the tensile strength of the Paulello/Stuart wire is 177 N/mm² higher, the Paulello/Stuart is 1.5mm longer, and is set at 3.5kg higher tension. The yield or capacity of the Roslau/Steinway wire is 3.6% higher than Paulello/Stuart.

Soundboard: The wider spectrum radiated in the Stuart sound to mic2, corresponded to the spectrum which vibrated in the Stuart soundboard. Fnd: STU=STE/ STU: 2nd ;3rd;4th ;5th ;6th 7th. Overall, at v20, the Stuart soundboard vibrations were 52% larger in amplitude than Steinway, for the note C2.
Instrument Volume Mic7: STU 81dB , STE 82dB
String Scale: For the note C2, the diameter of the Paulello/Stuart core wire is .125mm thicker, the cover wire is .47mm thicker and Stainless Steel, the tensile strength of the Paulello/Stuart wire is 481 N/mm² higher, the Paulello/Stuart is 235mm longer, and is set at 65.3kg higher tension. The yield or capacity of the Paulello/Stuart. wire is 46% higher than Steinway/Roslau.
