Pure sinusoids of 100, 200, 400, 800, 1600, 3200, 6400, and 12800 Hz are presented. This range covers a large part of the frequencies for which the human auditory system is sensitive. Though the sinusoids start at zero phase, one hears clicks at onset and offset of the tones, due to their sudden onsets and offsets. Compare this with the next sound example in which the onset and offset of the tones are more gradual.
