Here are some possibilities for what you might be referring to:
* Ideophones: These are words that imitate sounds or movements. They are common in many languages and often have a vivid, expressive quality. Examples include "bang," "whoosh," "tick-tock," and "swoosh."
* Idiophones: These are musical instruments that produce sound through the vibration of their own material, rather than by strings, membranes, or air columns. Examples include bells, cymbals, xylophones, and gongs.
If you provide more context or examples of what you're looking for, I might be able to give you a more precise answer.
