4.C4v81 MW mic1.

The Stuart 90dB, and Steinway 91dB, both radiated similar strong SPL levels of C4v81, to mic1. The Stuart sounds brighter. The number of upper partials illustrated in the .5s spectrogram below, are also similar for each sound, except the Stuart partials are more clearly defined, and the 8^th prt of the Stuart and the 7^th of the Steinway are more prominent. The high b7 in the Steinway is prominent in the sound, as is the high P5^th in the Stuart sound. Generally the Stuart sound is more harmonically balanced, and harmonious. The Steinway tonal spectra, changes more frequently than Stuart’s. The Stuart at 90dB, and Steinway 91dB, both radiated strong SPL levels of C4v81, to mic1. The Stuart sounds brighter. The number of upper partials illustrated in the .5s spectrogram below, are also similar for each sound, except the Stuart partials are more clearly defined, and the 8^th prt. of the Stuart and the 7^th of the Steinway are more prominent. The high b7 in the Steinway is prominent in the sound, as is the high P5^th in the Stuart sound. Generally the Stuart sound is more harmonically balanced, and harmonious. The Steinway tonal spectra changed more frequently than Stuart’s.

The main difference in the spectrums is the slower decay rates in the after-sound of the Fnd. and 2^nd prt. Both the Fnd. and 2^nd partials of the Stuart piano sound decayed at a slower rate than Steinway, between .5 and 2s.
