I’m something of a “not a scientist” myself
Same. Would like answers.
Did some searching. The paper from 2019 that discussed this -
We recorded 65 dBSPL (dB of sound pressure level) ultrasonic sounds 4 inches (10 cm) from tomato and tobacco plants, implying that these sounds could be detected by some organisms from up to several feet (meters) away.

I would like some weed. As a nonscientist, answers come secondary to weed.
Its legal to “not be a scientist” where I live
“I am not a scientist, I just smoke weed” needs to be a shirt.
a further idea: Front of the shirt says “I am not a scientist”
Back of the shirt says “I just smoke weed”
That explains why my fuzzy terrorist always wants to bite them.
Yes, if the plant is screaming at having its leaves torn, my little psychopath would absolutely be like “bite it harder!”
Wait… If the plants are whispering to my cat late at night. Is that why the little fucker spazzes out and goes crazy all over the house at 3 am?
Well, during the day plants are busy working (photosynthesising, defending, sticking pollen to bugs), they only have a chance to get socially chatty at night.
And cats love plant humour.
Except that of succulents. They crunch too much.That and all the ghost activity at 3am
what hz do ghosts talk at?
800!
Did some checking, out of curiosity.
And yeah. Interesting as hell.

Your move, vegans
Been waiting 17 years to pull that out, lol. Perfect.
I was absolutely expecting this song. I’m always expecting this song, but especially when I am fast asleep. The cries of the carrots…
CARROTS CAINT FIGHT BACK
Pineapples dissolve your mouth. Anything with capsaicin is non verbally asking you not to eat it.
…and anything with that many spikes on it is visually threatening your gullet, but it’s still delicious.
Oh good. I was worried they were defenseless.
Plants talk? As in rustle with movement or communicate through sound? Can plants hear? The world is amazing, I’ll be on Wikipedia for a few.
There are high frequency sounds that they emit when they experience certain stimuli, for example when not having enough water or leaves being torn. As far as I know some other plants or insects might be evolutionarily tuned to recognize those sounds and react to them. So yes, in a way plants can talk.
does that mean cats hear house plants scream while they are chewing on their leaves
It’s why they do it!
I’m not a cat or a plant scientist.
How do we know that sound signals recorded aren’t just from the release of biomolecules? Using the nervous system to produce sound is a more intentional process than the release of biomolecules for chemical signaling, which is something even simple multicellular organism do
You’re right that it doesn’t have to be talking. But it is a sound cats and dogs can hear. They do hear the plant noise, which is cool.
Right, but what’s the source of the sound? If it’s not intentionally produced, but rather a chemical reaction or reaction byproduct, then it says something different about plant communication
I agree, I just don’t think it’s that relevant to the post, which was more about how our pets experience the world.
The sounds produced by plants aren’t used for communication, at least as far as I’ve understood it. They are, as you say, just sounds produced as part of other processes. They aren’t talking any more than a tree talks when in creaks in the wind.
This is what happens when you get too high and Dr Dog - Listening In is playing
That’s actually the first time I’ve seen Dr Dog referenced in the wild (outside of Pat Finnerty’s channel.)
Also wild seeing this…I had never heard of them till I started dating my gf. She and most of her friends are big fans and I just saw them live a few weeks ago.
“I can hear the innermost thoughts of plants” - yup, sounds crazy to me! (Therefore let’s do it - make it happen!:-)
Is it possible to record those higher frequencies and then turn them down so I can hear how noisy it is for my dog at home?
Probably. If astronomers can convert the radio noise stars make into audible sound - and they can - then I don’t see why we couldn’t pitch adjust background noise to human-audible levels.
I’m not 100% on the pitching down bit, but key would be to get a mic that has those frequencies in its range.
You also need to have a sampling rate that’s equal to 2x the highest frequency you want to capture.
Sorry to link to CNN but I was skeptical and here’s a good enough summary
https://www.cnn.com/2023/03/30/world/plants-make-sounds-scn/index.html
It would be really neat if someone made a sensor that could tell you whether your plant needs to be watered.
Yeah, I’ve messed around with water sensors before. I just thought it would be neat to measure it via stress on the plant itself.
An RPI to measure moisture seems complete overkill. There’sESP Home for small sensors https://www.instructables.com/Building-a-Wireless-Soil-Moisture-Sensor-With-ESPH/
Pi picos are pretty good for iot projects like that. ESP are more power efficient, but a pi can be more self sufficient. I think it depends on the project.
The linked project recommended a Pi3 though.
Ah, that’s just overkill.
