Over 70 years ago, Roald Dahl proposed that plants could scream in a fictional story called The Sound Machine. He suggested they could shriek — …
, the world has most likely always been a noisy place.
“Even in a quiet field, there are actually sounds that we don’t hear, and those sounds carry information,” senior author. Hadany is an evolutionary biologist and theoretician at Tel Aviv University. Some animals can also hear the plants scream and make noise. The fact that some animals can hear the higher-pitched noises that plants emit suggests that there may be some acoustic interaction happening, Hadany says. Further, scientists say dehydrated plants have a different sound than well-hydrated plants.
It’s an exciting discovery that does pay some credit to Dahl’s story from 1949. Of course, the sounds emitted by the roses as they are cut in that story are much different from the popping noises that scientists observed during their study. While plants might not scream in a shrieking kind of way, it is interesting to see that they make noise and communicate audibly with the world around them. Perhaps this communication plays some part in how other creatures interact with those plants—such as bees or other pollinators. You canWe still don’t know much about this occurrence, including how the plants create these sounds in the first place.
