Onomatopoeia.
Imagery is incorrect as poets use that in order to help a reader visualize the scene or actions within the poem.
Simile is incorrect as similes are used to make analogies or comparisons between two objects or things.
Personification is incorrect as it is used to give a non-human being humanistic traits, for example, "The wind sang throughout the cold winter night."
Onomatopoeia, however, is correct as this is used to term sounds within a poem such as Wham! Bam! etc.
Hope this helps!
