Words for noises and sounds

On thursday i attended an art exhibition on the theme of silence. First off was a speaker who rattled on about the differences between sound and silence. Most of the time he seemed to be stating the obvious. Somehow i started thinking about words we use to describe sounds and, since i was bored, i started scribbling some of them down. Here they are:

English seems to be more varied than spanish... At any rate, words that describe sounds tend to be, in general, much shorter and more onomatopoeic in english than in spanish, and so the sounds they define seem to be much more precise and easier to recall (although maybe it is my command of spanish that is sinking).

Onomatopoeic words are everywhere in english. When you say "brush", you can hear its stiff bristles rasping against the thick hairs of a tangled mat of wool. When you say "clump", the four consonants plonking around that lonely "u" mirror the compactness of the clump itself, forming, coming together. And who can't hear the hooting in "owl"?

Of course, many spanish words also have clear onomatopoeic origins, but they have moved farther away from the original sound they describe. You can hear the "cry" in "grito", for instance, but that "to" at the end has been added by the necessities of gender and conjugation, so pervasive in romance languages. Still, when i say "rueda" (wheel), i fancy i can hear the rumble of heavy wooden carts rolling on uneven ground.

Anyway, what is the meaning of thinking about this? What can be its utility?
