The tone perception data stem
from an experiment of Cohen (1980) and have been analyzed in de Veaux
A pure fundamental tone was played to a
trained musician. Electronically generated overtones were added, determined
by a stretching ratio of

asked to tune an adjustable tone to the octave above the fundamental tone.
