Abstract
Distortion product otoacoustic emissions (also known as
combination tones) are sounds generated within the listener’s
ears upon physical and physiological interactions between
spectral components in a given auditory input. The
relationship between sounds generated by loudspeakers and
sounds generated in the listener's ears offers fertile ground for
the exploration of spatial depth in music. The author’s On the
Sensations of Tone is a series of compositions that provoke
ear tones to create an additional spatial dimension in each
piece. Following a brief overview of the history and
mechanisms behind otoacoustic emissions, this paper
discusses techniques for composing with the phenomenon as
used in On the Sensations of Tone VII (2015).
