Stimuli from Consonance Study, page 3
These pages contain example stimuli from
the paper "Individual Differences Reveal the Acoustic Basis of
Consonance" by
McDermott, Lehr, and Oxenham (Current Biology, 2010). The paper can be
downloaded here.
Quicktime must be installed for the sounds to play. HEADPHONES ARE ESSENTIAL FOR THIS PAGE
as the stimuli here
are
dichotically presented.

Figure 2, parts b&d
(Beating test stimuli and
their average pleasantness ratings):
Fig. 2b&d. Beating Test Stimuli. (b) Schematic frequency
spectra
for beating test stimuli. Each stimulus was a pair of pure tones
(single frequencies), and was presented diotically (both tones to both
ears), or dichotically (one tone to each ear). (d) Mean pleasantness
ratings of beating test
stimuli as well as some others from the study (see second page of
examples). Dichotic presentation largely eliminates beating, and
produces higher ratings.
Example diotic tone pairs
(audible beating):
We include the larger of the two intervals used.
