How to classify/categorize sounds

I run animal experiments which involve sound recognition
and/ordiscrimination.  Many various sound stimuli are used (e.g.,
tones, instruments, animal sounds (including birds), machines,
artficial sounds, knocks, bells etc.).  Is it possible to describe
quantitatively such various sounds (along multiple dimensions, I
suppose) in order to find quantitative indices of dfference, either in
multidimensional space, or along a single dimension?

Any help would be greatly appreciated.
