I like the way you said "silent wind howls." It was a beautiful contrast, especially because you obtained it in only one line.

As to fixing the syllable count, my suggestion would be:

The silent hill howls.
Trees, a hill, awoken by
new technology.

It sounds a little choppy, but it wouldn't change too much of the wording.

Anyway, nice work!

I guess howls can be one syllable (though I see it as 2), but technology is not one syllable. So I think you need to work on the haiku aspect of it.

I do think the description was interesting, going from nature to technology. I like how it's ambiguous so you can make your own meaning, but I also like how you explain your meaning behind it because I like knowing author's inspirations.
