I guess that a significant part of the Auditory list is now tired of this
debate, but let me nonetheless come to the rescue of Christian (briefly):
Peter, the observation you report is not consistent with observations
described in the last paragraph of K&D's General Discussion. The
discrepancy can be explained by supposing that your filtered click trains
were not mixed with low-pass noise, which gave rise to spectral artifacts
(audible combination tones at low frequencies).
