Three different auditory representations—Lyon’s cochlear model,
Patterson’s gammatone filterbank combined with Meddis’ inner
hair cell model, and mel-frequency cepstral coefficients—are analyzed
in connection with self-organizing maps to evaluate their
suitability for a perceptually justified classification of sounds. The
self-organizing maps are trained with a uniform set of test sounds
preprocessed by the auditory representations. The structure of the
resulting feature maps and the trajectories of the individual sounds
are visualized and compared to one another. While MFCC proved
to be a very efficient representation, the gammatone model produced
the most convincing results.
