Answer:
A poetic device used to imitate natural sound is onomatopoeia.
Step-by-step explanation:
An onomatopoeia is a word that imitates, resembles, or suggests the natural sound it describes or represents. Words like "clash," "smash," "clap," "pop," "bang," "cough," "moo," "whoosh," "swoosh," and "splash" are all examples of onomatopoeia. These poetic devices are often used to contribute to the overall mood of a poem, to evoke feelings or to make the ideas more memorable.
