Abstract
In data sonification research, there is a well-known perceptual
problem that arises when abstract multivariate datasets of a
certain size and complexity are parametrically mapped into
sound. In listening to such sonifications, when a feature
appears, it is sometimes difficult to ascertain whether that
feature is actually a feature of the dataset or just a resultant of
the psychoacoustic interaction between co-dependent
parametric dimensions. A similar effect occurs in visualisation,
such as when parallel lines can appear more or less curved on
different backgrounds. Couched in psycho-philosophical terms,
we can ask whether this failure is related to classical
phenomenology's inability to produce an eidetic science of
essential invariant forms that involve no assertion of actual
material existence, or to there not yet having been found some
generalisably acceptable limits from heuristically tested
mappings. This paper discusses the nature of this problem and
introduces a sonification research project based on embodied,
non-representational phenomenal models of perception.
