English has the word onomatopoeia which, according to dictionary.com, is a "formation of words in imitation of sounds." For example, as you have given, "crash" "bang" or even "pow".
If, by "meaningful acronym" you mean an arrangement of letters abbreviating a phrase into a pronounceable word, the proper word to use in English is "acronym." An acronym, by DEFINITION, **MUST** be a pronounceable word. SNAFU, QANTAS, SMART, QUEST, these are all acronyms. Any other combination of letters abbreviating a phrase into gibberish is an ABBREVIATION.
The proposed term "apronym," if it made any linguistic and etymological sense, would be redundant at best. As it is, the proposed term is illogical and ungrammatical. Why, you ask? I'll tell you.
The proposed term "apronym" is purported to be a combination of "APROPOS" and "ACRONYM" meaning "APPROPRIATE ACRONYM." Nice work, if "APROPOS" were defined to mean "APPROPRIATE" which is most certainly is not. This is one of the most common blunders in the English language and is usually the result of someone trying to use a $25 word where an everyday, pedestrian word will do.
What does APROPOS mean, you ask? It comes to us from French and it means "with regard to." For example:
Apropos the discussion in this forum, methinks the participants are largely confused sixth graders who haven't yet figured out the English language.
Hope that clears things up for you.
