Some physical and perceptual quantities correspond in a direct way:
frequency to pitch, and amplitude to loudness. We're interested in understanding
acuity in basic perceptual dimensions including pitch, loudness, and direction,
as well as the multi-dimensional makeup of sound properties like timbre,
distance and spectral fusion. A better understanding of what matters for
simulations of physical sounds, of what can be left behind when compressing
sound data and what might constitute analyzer front-ends for automatic
recognition of sounds results from gains in psychoacoustic research.
The psychology of perception often closely linked with artists' own
endeavors in manipulating illusions and creating synthetic realities.
