The Steinway sound is plotted by VSLM, to be 6dB lp louder than M19(STU),though audibly, the dB volume difference is not clear. The immediate brightness of the Stuart and the faster decay of the Steinway sound ii, is audibly distinctive, and illustrated in the energy curve and spectrogram below. Soon after the hammer strike, the SPL of the Steinway is heard to reduce, whereas the Stuart sound maintains more of a sustained tonal balance, with a slower steady-state reduction of SPL between .2 – .8s
The fundamental frequency of the Steinway is illustrated in the spectrogram below to be decaying at a faster rate than Stuart, between .2-.8s, after the initial or attack onset phase. The 2nd partial of the Stuart sound is significantly more present in the Stuart sound, influencing the brightness of the tone.244
