The piano sounds examined in this study have revealed a faster arrival to the maximum amplitude in the Stuart sound than the Steinway sound. In spectrograms 3.2 & 3.3, (below) the 2nd partial of the Stuart sound sounded at its maximum amplitude (dB) earlier in the time plot (3rd axis) than the 2nd prt. of the Steinway sound. The fundamental of C3v20 STE mic3 also peaked at its maximum amplitude (dB)later than the Fnd. in the Stuart piano sound.

A brighter tone colour is heard in the attack of the Stuart sound of C3v20STU MW mic3.There is also a deeper stable presence of the lower frequencies.
