Poetry Terms: Onomatopoeia

... the moan of doves in immemorial elms,
And murmuring of innumerable bees.

or

Kaboom!
Ka-blast
Way in the past
the miners mined for ore.
They searched for copper, iron and salt,
for that and much, much more.

Kaboom!
The bite
of dynamite
cut deep inside the earth.
The charge explodes revealing lodes
of minerals of worth.

Kaboom!
The dust,
the air so mussed
went swirling through the sky.
It was a sight, the dynamite
that made the mountains fly.

Kaboom!
The earth
was filled with mirth
so tickled by the boom.
The miner's pleasure,
each new found treasure
that followed each
Kaboom!

~" Kaboom"

Significance Movies have sounds, musics have effects, why wouldn't poems have onomatopoeia? :]
