If my edit to the question was correct, you cannot hear plants because they do not produce noise. If you prefer, we can hear plants if you consider wind going through it, or the snapping shut of the venus flytrap.
because it's too high pitched. humans can't hear sounds past a certain pitch.
Humans are heterotrophs. Plants are autotrophs.
Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
Almost all plants benefit humans
Plants are autotroph and humans and animals are heterotroph.

most animals like dogs can hear more higher pitches than us so they can hear it, you should not blow it too much, because it will hurt their ears.
in a way, but there are still some there, humans just cant hear them.
Dogs Dolphins and bats can all hear things that humans cant and so can cats but only sometimes.dogs ganot hear pepole but the can here dog whistle that we hardly hear.

As a hunter, dogs have evolved to have better hearing than humans. They can even hear voles/lemmings scurrying round under the snow!!
