The point here is that although maybe the mechanism here is just a mechanical process (although, what isn't?), the important thing are the responses to this, by the plant, other plants, and other organisms. Boiling water isn't going to take some action based upon it boiling nor are other organisms.

There’s a difference between a creature’s higher level response to a stimulus and just stuff that happens as a direct physical consequence of the stimulus.
It’s the same deal as boiling live lobsters. They aren’t actually screaming, even if you would be. That’s steam escaping. What the plant sound actually is, no clue. But I think the lobster scenario is what was being suggested upthread.
I remember hearing this at a seminar of new age things (I was doing an investigative thing at the time, which is why I was there)
So they already are!
We can now process it, so, as proactive evolution, it worked.
Before that,
> We know that certain animals are capable of hearing these sounds ... We still need to understand who is using this sound, what role does it play in the world, but it suggests many many possibilities // It's also possible plants themselves could react to these sounds, Hadany said. The same team found in a paper published in 2019 that plants can respond to the sounds of pollinators like bees. "They respond within three minutes by making sweeter nectar"
