The similarity of musical scales and consonance judgments across human
populations has no generally accepted explanation. Here we present evidence
that these aspects of auditory perception arise from the statistical structure
of naturally occurring periodic sound stimuli. An analysis of speech sounds,
the principal source of periodic sound stimuli in the human acoustical
environment, shows that the probability distribution of amplitude-frequency
combinations in human utterances predicts both the structure of the chromatic
scale and consonance ordering. These observations suggest that what we hear is
determined by the statistical relationship between acoustical stimuli and
their naturally occurring sources, rather than by the physical parameters of
the stimulus per se.
