I just had a random thought about this and I wanted to run it by here:
The experimental procedure calls for a low-pass filtering of the signal. Does low-pass filtering significantly affect the perceived volume? Could the low-pass filter's effect on the perceived loudness be the perceived trait here? It is well-documented that decrease in loudness is perceived as decrease in quality. By slightly amplifying the filtered signal, could the perceived difference disappear? So then, could the simple existence of the higher-order harmonics affect the overall power-spectrum (I'm aware that it will obviously be different in the frequency domain) significantly enough to be perceptible? -------------------- (atrix|(fb2k->e-mu 0404 usb|audio 8 dj))->hd280|jvc ha-fx35-b

Well, the 4.7us time constant does decrease the level of the 7 kHz fundamental by 0.18 dB, which he mentions in his paper. According to a description in his paper of another experiment (done by a different author), the just noticeable difference is 0.7 dB at that frequency.
