The slower rate of decay in the fundamental both in the onset and after-sound, has influenced a momentary slower after-sound decay rate at 3s. (ii). A wider spectrum was observed with longer durations of the 3rd, 4th 5th and 6th partial frequencies. The wider spectrum was also observed in at the Stuart onset, with larger amplitudes of the 3rd, 4th, 5th & 6th partial frequencies.
