Researchers believe that plants may be making noises to alert other plants and animals around them. They are just noises that human ears cannot hear.
However, technology today is enabling us to hear them for the first time, and scientists are studying how plants respond when in distress. They emit certain aromas. They change colors. The change shapes. And, yes, it's likely they also make noises.
People have been talking to plants for centuries. We're just now learning that we need to listen to them as well.
This, according to a study published in 2023, could be one of the ways in which plants communicate their distress to the world around them. "Even in a quiet field, there are actually sounds that we don't hear, and those sounds carry information. There are animals that can hear these sounds, so there is the possibility that a lot of acoustic interaction is occurring," said evolutionary biologist Lilach Hadany of Tel Aviv University in Israel. "Plants interact with insects and other animals all the time, and many of these organisms use sound for communication, so it would be very suboptimal for plants to not use sound at all."
